Finding Missing Side Lengths in Right Triangles

Miss Casius explains the Pythagorean Theorem, focusing on identifying triangle sides and using the theorem to find missing side lengths. She demonstrates how to calculate both missing hypotenuses and legs, emphasizing the difference in approach. The video includes examples and mixed problems to reinforce understanding.

What are the names of the shorter sides of a right triangle?

• Legs

• Hypotenuse

• Diagonals

• Base and Height

What is the formula of the Pythagorean theorem?

• a^2 = b^2 + c^2

• a^2 + b^2 = c

• a + b = c^2

• a^2 + b^2 = c^2
