Study Notes
Triangle Properties
- If A = 90 degrees, then the triangle is a right triangle.
- If a triangle has sides of lengths 6, 5, and 9, then the radius of the circle circumscribed about the triangle can be found.
- If angle A = 90 degrees, then the triangle is a right triangle.
Algebraic Expressions
- If x = 2 and y = 3, then x^2 + y^2 = 2^2 + 3^2 = 4 + 9 = 13.
Triangle Sides
- If a = 2, b = 3, and c = 4, then these values represent the lengths of the sides of a triangle.
