Sorry guys if its a bit late :)

Okay so today we talked reviewed a few 4.2 questions then we talked about similar triangles. Here are the notes we took ! :

Similar Triangles

Similar=Same

Rules for Similarity

SAS- Side,Angle, Side

ASA-Angle, Side, Angle

SSS- Side,Side,Side

If a triangle has corresponding sides that are proportional, then the triangles are similar. (SSS)

If a side and another side are proportional and the angle is congruent then the triangles are similar (SAS)

If two angles are congruent and one side is proportional then the triangle are similar. (ASA)

Kinds of Triangles !

Right Angle

-one angle is 90 degrees.

Isosceles

-two sides equal

-two angles equal

Scalene

-three unequal sides

Obtuse

one angle> 90 degrees

equilateral/equilagular

-all sides equal
