Pink Friday, this is the solution:
As you can see, here we have a 90-45-45 triangle, that is a special type of isosceles right triangle, where two legs are congruent to another, and the non-right angles measure 45 degrees.
Upon saying that,
Hypotenuse = √2
Now, we find the length of the legs, using the Pythagorean Theorem:
Leg 1² + Leg 2² = √2²
Leg 1² + Leg 2² = 2
1 + 1 = 2, because Leg 1 and Leg 2 are the same length.
• HD = 1

• RD = 1
