Right AngledTriangles Key points
Hypotenuse • The longest side of a right angled triangle • Always opposite the right angle Hypotenuse
Pythagoras’ Theorem • The two smaller sides, squared and added together equals the hypotenuse squared. • A2 + B2 = C2 • Only works for right angled triangles
Find the length of ‘j’ • To find ‘j’, use P.T. • Label the hypotenuse. • 122 + j2 = 152 144 + j2 = 225 j2 = 81 j = 9 cm 15cm hyp 12cm j
I hope this helped I don’t want to have to say
That’s all folks! The end
