Determine the missing length of a figure using special right triangle

The video tutorial explains how to determine missing lengths in geometric figures using special right triangle relationships, specifically focusing on 45-45-90 triangles. The instructor demonstrates how to create such a triangle within a figure, apply known relationships, and calculate unknown lengths using given measurements.

What is the relationship between the lengths of the sides in a 45-45-90 triangle?

• The legs are equal

• The hypotenuse is twice the leg

• The hypotenuse is equal to the leg

• The legs are half the hypotenuse

What is the total distance Y calculated in the text?

• 10

• 11
