New ReviewIn this math video lesson, students analyze a graph with six plotted points and determine which point could be removed so the relation becomes a function. The exemplar solution models how to apply the vertical line test, showing that...

In this shorts video we will rotate a segment 180 degrees. Will will understand that a rotation of 180 degrees is two 90 degree turns. We will rotate about a point or vertex, so, this will be the center of rotation. We will graph the...

In this Grade 6 math lesson, we review how to find which of four points is a given distance from a graphed point on the coordinate plane. You’ll learn how to determine distances when moving right, left, up, and down from a given point....

You will solve real-world application problems modeled by shapes in coordinate planes.

This video, entitled "Rotating Line Segments," explains how line segments can be rotated on a coordinate plane.

A video entitled "Practical Examples" that covers transformations the result in similar figures, such as dilations and translations.

In this video, we investigate how to find trig ratios when given other ratios. First, we define all six trig ratios, then we examine for which quadrant each angle is positive and negative. Then, we work two examples.

Find all six trig ratios given a point on the terminal side of theta. In this video we work this common type of problem. We use the Pythagorean Theorem to find "r" (hypotenuse), and then use the given "x" (adjacent) and "y" (opposite) to...

How do you graph y=tan(x) and y=cot(x)? Why do the graphs look the way they do? How do I know where the asymptotes and zeros are for each graph? This video answers all these questions and derives the graphs for these two periodic trig...

What is the polar coordinate plane and how do we convert points between rectangular and polar form? We start this video by graphing polar points, then we learn how to convert between polar and rectangular/Euclidean form.

This video explains how changing the slope (m) and the y-intercept (b) in the slope–intercept form affects the graph of a linear function. It shows that increasing the absolute value of m makes the line steeper, while bringing m closer...

The video explains how to solve quadratic equations when they're in factored form by understanding the link between their linear factors and the quadratic itself.

In this math video we will learn about relationships & the coordinate plane. We will be presented with a real world situation that is shown on a graph. We will understand that the graph represents the relationship between two quantities....

In this math video we will be plotting points on a graph. We will learn that an ordered pair is written in the form (x, y) where x tells us the horizontal distance to travel right from the origin followed by a vertical distance of y. We...

In this math video we will learn how to write the equation of a circle. We will review the formula to write the equation of a circle given the center (h, k) and the radius r. We will understand that h represents the x coordinate of the...

In this math video we will find distance in the coordinate plane. We will understand that we can create a right triangle using a coordinate plane. We will also understand that the Pythagorean Theorem applies to any right triangle and is...

This video explains the concept of translation in mathematics using the analogy of an ice skater gliding across the ice. It demonstrates two methods for translating figures on a coordinate plane, emphasizing the importance of maintaining...

In this math video we will use a relationship to graph a line. We will interpret the real world situation given as an ordered pair (x, y). We will use the unit rate ( or slope) to create and write ordered pairs. We will plot the points...

In this math video we will discuss similar triangles & slope. We will be presented with the graph of a line and two triangles arranged with their longest side on the line. We will have four statements to choose the one statement that...

In this math video we will learn how to draw an isosceles triangle in a coordinate plane. We will be given three important fact about a triangle to construct a triangle in the given coordinate plane. We will first understand how to...

In this math video we will perform a transformation to a figure in the coordinate plane of rotate 180º about the origin. We will be presented with a quadrilateral in a coordinate plane graphed in the first quadrant. We are asked to...

In this math video we will reflect a figure in the x-axis. We will identify the line of reflection first. We will understand that a reflection is a "flip" over the line of reflection. Each vertex of the figure must be reflected over the...

In this math video we will identify & determine congruent transformations. I will introduce a three part constructed response question. We are presented with a coordinate plane with two parallelograms. Part A asks us to determine what...

In this math video we will identify a reflection in the y-axis. We will begin by identifying the line of reflection. We will understand that every vertex must be reflected the same distance over the line of reflection. We will reflect...
