Countdown to Exams - Day 61 - Congruence criteria for triangles

Countdown to Exams - Day 61 - Congruence criteria for triangles

On day 61, we focus our attention on the Congruence criteria for triangles. There will be questions that ask you to state why two triangles are identical. Here you will need to examine the side lengths and angles of the triangle and see which of the four categories they fit into. Side, Side, Side (SSS), Side, Angle, Side (SAS), Angle, Side, Angle (ASA), Right Angle, Hypotenuse, Side (RHS).

You may have to flip/rotate the triangles in your head (or use tracing paper) to see if they match up and identify which criterion to use.

In the video below, Matt will take you through the four congruence criteria for triangles.
