Pythagoras' Theorem
L.I. To use Pythagoras' Theorem to calculate the short side of a right angled triangle
S.C. I understand how the formula for finding the hypotenuse can be changed to find the short side
I can find the short side of a right-angled triangle using this formula
I can check my answer is smaller than the hypotenuse
I can do all of this in a real life problem.
Angles in a circle and a semi-circle
L.I. To continue yesterdays ideas of triangles in a circle and using Pythagoras and introducing the idea of angles in a semi-circle and using trigonometry and Pythagoras to solve these questions.
S.C. I understand that two radii connected by a chord create an isosceles triangle
I can use Pythagoras' Theorem to find missing sides
I understand that a two chords touching the diameter at opposite ends and meeting at their other end creates a right-angled triangle inside the semi-circle
I can use Pythagoras' and Trigonometry to answer questions using this fact
