Is triangle ABC a right triangle? How do you know?

• Yes. Because there's a right angle in the triangle.

• No. Because there isn't a right angle at any vertex.

• No. Because the sum of the squares of the legs is NOT equal to the square of the hypotenuse.

• Impossible to determine.

Consider the quadrilateral ABCD with vertices A(-2, -1), B(2, 2), C(5, -2), and

D(1, -5). Graph using Desmos or GeoGebra.

A) Prove that the quadrilateral is a rectangle. Justify your reasoning.

• Quadrilateral, two opposite and parallel sides without right angles.

• Quadrilateral, four right angles, one pair of opposite congruent sides.

• Quadrilateral, adjacent slopes equal to each other's negative reciprocals, opposite sides are congruent, all vertices are right angles.

• Quadrilateral with exactly one pair of opposite and parallel sides.
