3. Ch. 7-4 Classifying Triangles and Quadrilaterals
Acute Triangle has 3 acute angles
Obtuse Triangle has one obtuse angle
Right Triangle has one right angle
Equilateral Triangle has 3 congruent sides
Isosceles Triangle has at least two congruent sides
Scalene Triangle has no congruent sides

4. Example 1: Classify each triangle below
Example 1: Classify each triangle below. Remember to classify them according to their angles and sides.
Isosceles Obtuse Triangle
Scalene Right Triangle
Acute Equilateral Triangle

5. Exactly one pair of parallel sides Parallelogram:
Quadrilateral:
4 sides
Trapezoid:
Exactly one pair of parallel sides
Parallelogram:
Both pairs of opposite sides parallel
Rectangle:
4 right angles
Rhombus:
4 congruent sides
Square:
4 right angles and 4 congruent sides

6. Example 2: Classify each quadrilateral below with its best name.
The quadrilateral has 2 pairs of sides that are parallel and all of its sides congruent
Therefore, the best classification would be a rhombus
The quadrilateral has 2 pairs of sides that are parallel and 4 right angles
Therefore, the best classification would be a rectangle
The quadrilateral has exactly 1 pair of sides that are parallel
Therefore, the best classification would be a trapezoid

7. Example 3: See if you can name all shapes shown in the picture that were discussed in this lesson
There are 3 isosceles acute triangles: the pine trees and the roof
There are 7 rectangles: the chimney, the NEW sign, the middle fence, the 3 windows, and the door
There is one trapezoid: the bottom part of the chimney
There is one square: the house itself
