A quadrilateral in which both pairs of opposite sides are parallel. What is a parallelogram? A parallelogram in which at least one of the angles is a right angle. What is a rectangle? A parallelogram in which at least two consecutive sides are congruent. What is a rhombus? A parallelogram that is both a rectangle and a rhombus. What is a square? A quadrilateral with exactly one pair of parallel sides. What is a trapezoid? A triangle in which no two sides are congruent. What is a scalene triangle? A triangle in which at least two sides are congruent. What is an isosceles triangle? A triangle in which all sides are congruent. What is an equilateral triangle? A triangle in which all angles are congruent. What is an equiangular triangle? A triangle in which one of the angles is a right angle, also including the hypotenuse and legs. What is a right triangle? Any segment or angle that is congruent to itself. What is the Reflexive Property? Three sides of one triangle are congruent to the corresponding sides of the other triangle. What is the SideSide-Side Postulate? Two angles and the included angle of one triangle are congruent to the corresponding parts of the other triangle. What is the SideAngle-Side Postulate? Two angles and the included side of one triangle are congruent to corresponding parts of the other triangle. What is the AngleSide-Angle Postulate? After it is known that two triangles are congruent, matching angles and sides of the triangles are proven congruent. What is CPCTCCorresponding Parts of Congruent Triangles are Congruent?
