Use the triangle congruence criteria SSS, SAS, ASA, and AAS to determine that two triangles are congruent.

Learn all about the basic properties of a cone. This lesson targets the ASA congruence theorem using real-life examples and has interesting interactive practice questions.

[Free Registration/Login may be required to access all resource tools.] In this lesson students prove two triangles are congruent with the Angle-Side-Angle and Angle-Angle-Side shortcuts. Students examine guided notes, review guided...

See how triangles are congruent where all corresponding angle pairs and sides are the same.

In this task, learners must prove that angles and triangles are congruent and that a parallel line passes through the midpoints of two sides of the larger triangle. Aligns with G-SRT.B.4.

In this task, students are asked to draw a quadrilateral so that no two sides are congruent, no two angles are congruent, and no two sides are parallel. The task gives students the opportunity to prove that if we join the midpoints of a...
