4. the perpendicular drawn from the vertex of the triangle to the opposite side
7. three dimensional, geometrical shape, that has all its surface points equidistant from a common point.
8. a factor of a number that, when multiplied by itself, gives the original number
13. a two-dimensional plane formed by the intersection of two number lines
14. A geometric figure or shape that has a three-dimensional structure
16. the square of the length of the hypotenuse of a right triangle equals the sum of the squares of the lengths of the other two sides.
19. irrational number, any real number that cannot be expressed as the quotient of two integers—
20. If the square of the length of the longest side of a triangle is equal to the sum of the squares of the other two sides, then the triangle is a right triangle.
