Unit 11: GeometryPart 2: Classify Two-Dimensional Figures​

MATH.4.6A/I can draw, label, identify, and describe types of angles using concrete and pictorial models with a right angle as my benchmark.​

​Let's Review

​Let's refresh our minds and review previous concepts from the unit.

Multiple Choice

Which term best describes the figure?

• Ray AB

• Line segment AB

• Point AB

• Line AB

Multiple Choice

Which term best describes the figure?

• Ray RST

• Line segment RST

• Angle RST

• Point RST

Multiple Choice

Which best describes parallel lines?

• They intersect at one point.

• They form one obtuse angle.

• They never meet.

• They form one acute angle.

Multiple Choice

Which names an obtuse angle in the figure?

• Angle JHG

• Angle FHJ

• Angle GHK

• Angle FHK

Multiple Choice

Which type of angle is greater than a right angle?

• Acute and obtuse only

• Straight only

• Obtuse and straight only

• Obtuse only

Multiple Choice

Which names a straight angle in the figure above?

• Angle ABC

• Angle EBF

• Angle CBF

• Angle ABF

Open Ended

Will these lines ever intersect? How do you know?

Review Triangles​

​Then we learned about classifying triangles

Multiple Choice

How many pairs of parallel lines are in this shape?

• 0

• 1

• 2

• 3

Multiple Choice

What kind of triangle is this?

• Obtuse because it has 1 obtuse angle
• Right because it has 2 right angles
• Right because it has 1 right angle
• Acute because it has 2 acute angles

Multiple Choice

Dominick drew a triangle with one perpendicular line and 2 acute angles. What type of triangle is it?

• right

• acute

• double acute

• obtuse

Multiple Choice

How many acute angles must an acute triangle have?

• 2
• 1
• 4
• 3

Multiple Choice

What type of triangle is this?

• Obtuse
• acute
• straight
• right

​Then we ....

• ​classified 2-D figures

Multiple Choice

Name that shape.

• quadrilateral, rectangle
• quadrilateral, rectangle, square
• quadrilateral, parallelogram, rectangle
• quadrilateral, parallelogram, rectangle, square

Multiple Choice

If a quadrilateral has 4 equal sides, then it is a square. 

• TRUE
• FALSE

Multiple Choice

A ________ is any polygon that has 4 sides.

• square
• parallelogram
• quadrilateral
• trapezoid

Multiple Choice

Name this shape:
No right angles
4 equal sides
2 sets of parallel sides

• Square
• Trapezoid
• Rhombus
• Rectangle

Multiple Choice

Which quadrilateral is NOT a parallelogram?

• rectangle
• square
• trapezoid
• rhombus

Multiple Select

Select ALL attributes of a trapezoid.

• It is a quadrilateral

• It has 4 vertices

• It has 1 set of parallel lines

• Not all sides are equal length

Multiple Select

Select all the shapes that are classified as quadrilaterals.
