Time to think… Are these triangles congruent or similar and why?

Time to think…  Are these triangles congruent or similar and why? Similar because their angles are the same and their sides are in proportion

Time to think…  What type of angle is this?

Time to think…  What type of angle is this? Obtuse… more than 90°

Time to think… 75 º Find the missing angle: ?

Time to think…  The missing angle is 105 º

Time to think…  If a triangle has a 40 º angle and a 70º angle, what is the third angle?

Explain…  Why is a square a rectangle, but a rectangle not a square?

Explain…  Why is a square a rectangle, but a rectangle not a square?  A square is a rectangle because it has two pairs of congruent sides, two pairs of parallel sides, and four right angles. A rectangle is not a square because it does not have all 4 sides congruent.
