Classify Triangles and Quadrilaterals

Using this hierarchy of two dimensional figures, determine which of the following labels can be given to the shape below. Select three that apply.

• paralellogram

• polygon

• quadrilateral

• rectangle

Look at the hierarchy. Which figure can be placed below the rectangle in this hierarchy?* (A question like this is almost always on AIR test!)

• rhombus

• trapezoid

• square

• triangle

I am a triangle with all sides measuring less than 90 degrees. What am I?

• Right triangle
• Scalene triangle
• Acute triangle
• Obtuse triangle

What kind of triangle is this based on its side length?

• equilateral

• scalene

• isoceles

What is the biggest difference between a Trapezoid and a Parallelogram?

• The Quadrilateral family tree has them split

• One is a Quadrilateral and one is a Polygon

• A Trapezoid has 2 acute angles and a Parallelogram has 2 Obtuse angles

• A Trapezoid has 1 pair of parallel lines and a Parallelogram has 2 pairs of parallel sides

A rectangle can also be called a...(select two other names)

• Parallelogram

• Trapezoid

• Rhombus

• Quadrilateral

• Square

Look at the sides and angles of this triangle. Which type of triangle is pictured?

• Equilateral Triangle

• Isosceles Triangle

• Scalene Triangle

• Obtuse Triangle

• Right Triangle

This triangle could be called (check all that apply)

• equilateral

• isosceles

• obtuse

• acute

• equilangular

A triangle has angle measurements of 26°, 59°, and 95°. What kind of triangle is it?

• acute triangle
• right triangle
• obtuse triangle
• none of the above

True or False: Trapezoids are quadrilaterals

• True

• False
