What figure has all sides are the same length or we call it a squished square?

Rhombus

Which figure is this?

heptagon

Which figure has two parallel sides and two sides that are not?

Trapezoid

All of these shapes are called ______ or ________.

This figure has opposite sides that are equal lengths, opposite angles are equal, and opposite sides are parallel. What am I?

Parallelogram

A triangle with all sides and angles are equal.

Equilateral triangle

A polygon with all vertices pushed out.

Convex

What is a regular polygon?

A polygon with ALL sides and ALL angles equal.

Which one is not a polygon? Explain why. A B C

B&C Not a closed shape. Line segments intersect. More than one interior.

Name 3 properties of polygons.

*A polygon is made up of line segments. *Sides must meet at endpoints to form angles and vertices. *The number of sides is the same as the number of angles and vertices. *All sides of a polygon must be connected end to end. *No two sides may touch except at a vertex. *A polygon can have any number of sides, as long as it has at least three. *A polygon can have only one interior.

The starting point on a ray is called an ______.

endpoint

True or False? One line can be named line AEB. Why?

False – Because you only name a line using 2 points not 3.

Name the line that intersects.

Line EF

The place where lines cross is called an ________.

intersection

If a right angle measures 90 degrees, a straight line measures ____ degrees.

180 degrees

The point where two line segments or rays meet to form an angle is called the ______.

Vertex

What is the name of this special angle and why is it special?

A right angle is special because it measures 90 degrees and is a square corner.

What are two names for this angle?

Angle APB or Angle BPA

These are examples of ____ angles.

acute

Which angle is obtuse? A B C

B – Obtuse angles are greater than 90 degrees.

What is a tool for drawing and measuring circles and lines?

compass

Give 2 names for this shape?

Pentagon Polygon Regular Polygon

Lines that never intersect are called _____.

parallel

This is an example of an ___________.

Inscribed square

Two circles that don’t intersect but have the same center are called ________.

Concentric circles

_______, and ____ are parallelograms.

Squares, rectangles, and rhombuses
