Learn how to find the angles in right-angled triangles with this BBC Bitesize Maths article. For students between the ages of 11 and 14.

For two right-angled triangles, if an angle (other than the right angle) is the same, the third angle will also be the same. This is true because angles in a triangle add up to 180°.

Third angle = 180 – 90 – 36.87 ≈ 53.13 degrees In conclusion, by using trigonometric ratios and inverse trigonometric functions, you can calculate the angles in a right triangle when given side ...

It allows them to practise calculating angles in isosceles and scalene triangles. Note that unlike most treasure hunts, this one has the added feature that the answers give an encrypted clue. Pupils ...

It categorizes triangles into equilateral, isosceles, scalene, obtuse, right, and acute based on their sides and angles. The video also covers the concept of congruency, demonstrating how two ...

Students are often unsure why angles in the same segment of a circle have to be equal. Colin Foster explains how to make it ...
