S1 Topic 10 Similar Triangles
... 3. The teacher should ask students what they have noticed about the triangles (e.g. the angles are equal, the sides are proportional). 4. The teacher should then discuss with the students and point out that the shape of a triangle is determined by its angles. Thus, the angles will not change when th ...

... If two angles and one side in one triangle are congruent to the corresponding two angles and one side in another triangle, then the two triangles are congruent. This idea encompasses two triangle congruence shortcuts: AngleSide-Angle and Angle-Angle-Side. Angle-Side-Angle (ASA) Congruence Postulate: ...
