Math Chapter 12: Midpoint Theorem and Geometry

The angle at the midpoint of a triangle's side measures 90 degrees.

The line segment joining the midpoints of two sides of a triangle is parallel to the third side and half its length. (correct)

The perpendicular drawn from the vertex of a triangle to the opposite side bisects the side.

The line segment bisecting the angle of a triangle is perpendicular to the opposite side.

The sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse. (correct)

The product of the lengths of the legs is equal to the area of the right triangle.

The sum of the lengths of the legs is equal to the length of the hypotenuse.

The ratio of the hypotenuse to the opposite side is equal to the sine of the angle.

An angle formed by two radii of the circle.

An angle whose vertex is on the circumference of the circle and is equal to 90 degrees.

An angle whose vertex is on the circle and whose sides contain chords of the circle. (correct)

An angle whose vertex is at the center of the circle.
