   What are the sides of the Pythagorean theorem?

   • Before we state the Pythagorean Theorem, we need to introduce some terms for the sides of a triangle. Remember that a right triangle has a 90° angle, marked with a small square in the corner. The side of the triangle opposite the 90°90° angle is called the hypotenuse and each of the other sides are called legs.

   What does area mean?

   • Simply speaking, area is the size of a surface. In other words, it may be defined as the space occupied by a flat shape. To understand the concept, it's usually helpful to think about the area as the amount of paint necessary to cover the surface. Look at the picture below – all the figures have the same area, 12 square units:

   Feb 13, 2022 · Angle measures: m∠A + m∠B + m∠C = 180 ∘. The sum of the measures of the angles of a triangle is 180°. Perimeter: P = a + b + c. The perimeter is the sum of the lengths of the sides of the triangle. Area: A = 1 2bh, b = base , h = height. The area of a triangle is one-half the base times the height.
