Answer:
Explanation:
A 45-45-90 triangle, also known as an isosceles right triangle, is a special right triangle where two of its three sides are congruent, and the third side is the hypotenuse. In other words, the triangle has two 45-degree angles and one 90-degree angle.
The ratio of the sides of a 45-45-90 triangle is always 1:1:√2. That is, the length of each leg (the two congruent sides) is equal to x, and the length of the hypotenuse (the third side) is equal to x√2, where x is any positive number.
