Unit 2 Geometry

What conjecture is possible to prove?

• If the four angles in a quadrilateral are congruent to the four angles in another quadrilateral, then the two quadrilaterals are congruent.

• If the four sides in a quadrilateral are congruent to the four sides in another quadrilateral, then the two quadrilaterals are congruent.

• If the three angles in a triangle are congruent to the three angles in another triangle, then the two triangles are congruent.

• If the three sides in a triangle are congruent to the three sides in another triangle, then the two triangles are congruent.

Select the statement that must be true.

• Parallelograms have at least one right angle.

• If a quadrilateral has opposite sides that are both congruent and parallel, then it is a parallelogram.

• Parallelograms have congruent diagonals.
