Classifying triangles by angle measure

• When you classify triangles by their angle measures, you use the words acute, right, and obtuse.

  
  

• Let's find out what those words mean!

Acute Triangle

• An acute triangle has three acute angles.

• Acute angles measure less than 90°

• This is an example of an acute triangle.

Multiple Choice

Which of these is an acute triangle?

Right Triangle

• A right triangle has one angle.

• Right angles measure exactly 90°.

• This is an example of a right triangle.

• Notice that all of the angles add up to be 180 degrees.

• The angles in a triangle always add up to 180 degrees

Multiple Choice

Which of these is a right triangle?

Obtuse triangle

• An obtuse triangle has one obtuse angle.

• Obtuse angles measure more than 90°.

• This is an example of an obtuse triangle.

Multiple Choice

Which of these triangles is obtuse?

Dropdown

A triangle has one pair of perpendicular sides and two acute angles.

Types of Quadrilaterals

A quadrilateral has four sides and four angles. Use what we have learned in class to classify each of the following quadrilaterals based on their sides and angles.

Trapezoids

• four sides and four angles

• one set of parallel sides

Multiple Select

Select all of the characteristics of a trapezoid

• four sides

• four angles

• only one set of parallel sides

• two sets of parallel sides

Multiple Select

Which of the following is a trapezoid? SELECT ALL THAT ARE TRAPEZOIDS

Parallelograms

• four sides and four angles

• two sets of parallel sides

Multiple Select

Select all of the characteristics of a parallelogram

• four sides and four angles

• opposite sides are equal

• only one set of parallel sides

• two sets of parallel sides

Multiple Select

Which of the following are NOT parallelograms? Select all that are NOT parallelograms.

Multiple Select

Some parallelograms have special attributes. Which of the following shapes also fit the description of a parallelogram? SELECT ALL THAT ARE PARALLELOGRAMS

Ask yourself, "Does this shape have 2 sets of parallel sides?" to find the parallelograms.

• square

• trapezoid

• rectangle

• circle

Rectangles

• have four sides

• have four right angles

• two sets of parallel sides

Multiple Select

Select all of the characteristics of a rectangle

• four sides and four angles

• opposite sides are equal

• four right angles

• two sets of parallel sides

Multiple Choice

Which of the following is a rectangle?

Multiple Choice

Why is this parallelogram not considered a rectangle?

• it doesn't have four sides

• it doesn't have two sets of parallel sides

• it doesn't have four right angles

Squares

• have four equal sides

• have four right angles

• two sets of parallel sides

Multiple Select

Select all of the characteristics of a square

• perpendicular lines

• four equal sides

• four right angles

• two sets of parallel sides

Multiple Choice

Which of the following is a square?

Multiple Choice

Rectangles and squares are very similar, but something must be true about a square to set it apart. What is the special attribute that a square must have?

• all angles are 90 degrees

• all 4 sides must be equal in length

• two sets of parallel sides

• four sides

Rhombuses

• have 4 equal length sides

• have opposite sides that are parallel

• opposite angles are equal to one another

Multiple Select

Select all of the characteristics of a rhombus

• perpendicular lines

• four equal sides

• four right angles

• opposite sides are parallel sides

Multiple Select

Which of the following are rhombuses? Remember, all sides must be equal and opposite angles must be equal. SELECT ALL THAT ARE RHOMBUSES

Multiple Choice

For the last question, we saw that a square is also a special type of rhombus. All squares are rhombuses but all rhombuses are NOT squares. Why do you think that is true?

• Rhombuses don't have to have 4 sides of equal length but squares do

• Rhombuses do not have to have right angles but square do

• Squares only have one set of parallel sides but rhombuses have two
