The line from C to the hypotenuse also forms a 45-45-90 right triangle. With this knowledge, the length of a & b are 22?2.

By the way, c = 22?2 * ?2 = 22 * 2 = 44.

Ok so the line from angle C (90 degrees) to the centre of the hypotenuse? So that this creates an opposite right angle?

From the angles given, the triangle is a 45, 45, 90 right Triangle. The line from C to the hypotenuse bisects the triangle forming 2 congruent triangles to the original. That distance is 22 so to find the hypotenuse of 1 of those 2 triangles you’d use the Pythagorean theorem

22^2 + 22^2 = c^2
c = 31.11

That hypotenuse is also the legs of the original triangle so a and b also equal 31.11

by dropping an altitude to c measuring 22″, you get another triangle with 45,45,90

22″ is opposite a 45 angle, so the other side is 22″ opposite the 45 angle

(22)^2 + 22)^2 = sideA^2
484 + 484 = sideA^2
968 = sideA^2

31.1126 = side a

side b = side a = 31.1126

a^2 + b^2 = c^2
968 + 968 = c^2

1936 = c^2
44 = c
