I love coffee. Like, a lot. You know who else loves coffee? Astronauts! And also the people who help them do awesome things in space (I think NASA might be powered by coffee). But how do astronauts actually drink coffee in space, aboard...

Pupil outcome: I can use my knowledge of shape properties to draw shapes accurately using rulers and protractors. Key learning points: - A protractor is used to draw and measure angles accurately. - Read the scale from zero on a...

Pupil outcome: I can describe static angles using the standard unit of degrees when compared to a right angle. Key learning points: - There are 90 degrees in a right angle - Acute angles are between 0 and 90 degrees - Obtuse angles are...

Pupil outcome: I can use the terms acute, obtuse and reflex when comparing angles to a right angle. Key learning points: - Angles are marked with a curve between the lines which have been rotated - Angles with a bigger turn are larger...

Pupil outcome: I can calculate with angles at a point, angles on a line and vertically opposite angles. Key learning points: - Angles that meet at a point can be identified in diagrams. - Angles that make a straight line can be...

Pupil outcome: I can recognise the right-angled triangle within a unit circle and use proportion to scale to similar triangles. Key learning points: - There are specific ratios within the two key right-angled triangles defined by the...

In this video, we define reference angles, learn formulas for reference angles, and learn how to calculate reference angles. Personally, I focus more on visualizing the angle itself vs memorizing the formula

We are getting to know angles with this quirky activity. I love how Alex's face lights up when he sees that a number of angles in each digit corresponds to its value.

In this video we explain the different types of angles in maths. We explain acute angles, right angles, straight angles, obtuse angles, reflex angles and full rotations. Two sets of practice questions and answers are at the end of the...

Mr. Addit describes the three main types of angles and the way that those angles can be measured.

Mr. Addit reviews points, lines, angles, and triangles and how to classify them.

Mr. Addit reviews right angles, acute angles and obtuse angles. He then measures a few angles. Next, he estimates the measurement of a couple angles and then measures to see how well he estimated.

Mr. Addit reviews the definition of “angle.” He then reviews right angle, acute angle, and obtuse angle and provides examples of each.

Mr. Addit reviews geometry fundamentals including: points, lines, line segments, rays, perpendicular and parallel lines, acute, obtuse, and right angles, and isosceles, scalene, and equilateral triangles. He also reviews polygons...

You could say that angles are some of the building blocks of geometry, and you've probably already seen lots of examples of angles in your life already. In this lesson, we'll go over the exact definition of an angle, how to name an...

A video entitled "Identify Angles" which discusses the different types of angles and how they can fit together to form other angles.

In this video, the teacher explains how to find the measure of an acute angle in a right triangle when only the side lengths are known. They introduce the concept of trigonometric ratios (sine, cosine, and tangent) and explain how to use...

In this video, we learn about solving for X in triangles using the sine ratio. By comparing the ratios of the length of the side opposite an acute angle to the length of the hypotenuse in right triangles, we can determine the value of X....

In this video, you will learn how to find the measure of an acute angle in a right triangle using the inverse sine function. The video explains the ratios of side lengths for the trigonometric functions and introduces the concept of...

In this video, the teacher explains how to use the tangent ratio to find the height of a flying plane. By setting up an equation using the tangent of the given angle and the known distance, the teacher demonstrates how to solve for the...

This video explains how to find the measure of an acute angle in a right triangle when only the side lengths are known. It introduces the concept of inverse trigonometric functions, specifically the inverse cosine function, to determine...

In this video, the teacher explains how to solve for X without using the tangent ratio. Instead, they introduce the cotangent ratio and demonstrate how it can be used to find the length of the leg adjacent to an acute angle in a right...

In this video, the teacher explains how to find the length of segment DG in a right triangle without using the cosine ratio. Instead, they introduce the secant ratio, which compares the length of the hypotenuse to the length of the leg...

In this video, we explore how to efficiently find the measure of one acute angle in a right triangle. We learn that the size of the angles in a right triangle is based on the length of the sides, and that the acute angles co-vary or...
