A polygon is a flat, closed plane shape made up of three or more line segments called sides TRUE OR FALSE:

TRUE !!!!!!!!!

TRUE OR FALSE: A QUADRILATERAL IS A POLYGON WITH TWO SIDES

A QUADRILATERAL IS A POLYGON WITH FOUR SIDES FALSE!!!!!!!!!!! A QUADRILATERAL IS A POLYGON WITH FOUR SIDES

A SIX SIDED SHAPE IS CALLED A _________?

HEXAGON!!!!!!!!

WHAT ARE THE NAME FOR QUADRILATERALS WITH FOUR EQUAL SIDES?

A SQUARE AND A RHOMBUS!! SQUARE RHOMBUS

NAME THE GEOMETRIC FIGURE EACH SIGN REPRESENTS:

Octagon Rectangle Triangle

CIRCLES ARE A TYPE OF POLYGON? TRUE OR FALSE: CIRCLES ARE A TYPE OF POLYGON?

A CIRCLE IS CURVED, NOT FLAT, AND IS NOT MADE UP OF ANY LINE SEGMENTS. FALSE!!!!!!!!!! A CIRCLE IS CURVED, NOT FLAT, AND IS NOT MADE UP OF ANY LINE SEGMENTS.

DOES A LINE EXTEND IN ONE DIRECTION OR TWO?

A line is a straight path that extends in two directions.

Do Perpendicular Lines Interest at: RIGHT ANGLES ACUTE ANGLES OBTUSE ANGLES

When perpendicular lines intersect, they create right angles.

Which is an example of parallel lines? B: C:

Parallel lines do not intersect B: Parallel lines do not intersect

If given the name <ABC, which angle is correct?

A: A B C Since B is the middle letter in the angle name, <ABC, B has to be the vertex of the angle.

Which direction would ray MB need to be moved to make an obtuse angle?

Ray MB would need to be moved to the left, to make an obtuse angle because an obtuse angle is greater than 90 degrees. B B M M R R

Congruent figures are the same shape, but can be different sizes? TRUE OR FALSE?

Congruent figures are the same shape AND size. FALSE!!!!!! Congruent figures are the same shape AND size.

If two figures are similar, are they A: The same shape, but different sizes? B: Different shapes, but the same size?

A: The same shape, but not necessarily the same size A: The same shape, but not necessarily the same size. Similar figures have to be the same shape, however, they can be the same or different sizes.

Similar but not congruent Are these figures: Congruent Similar but not congruent Neither

The figures are similar because they are the same shape, but not the same size.

Do all figures have a line or lines of symmetry? YES OR NO?

NO!!!!!!!!! All figures do not have a line of symmetry. Has line of symmetry Does not have symmetry

What is another name for a line of symmetry? A: A curved line B: A diagonal line C: A perfect line D: A fold line

Another name for a line of symmetry is a FOLD LINE! A line of symmetry separates a figure into two parts that math exactly. You can FOLD a shape along the line(s) of symmetry and the pieces will lay directly on top of another.

How many lines of symmetry does this figure have? A: One B: Three C: Four D: Five

Which triangle is an equilateral triangle? B C

A scalene triangle has three sides and angles that are equal? TRUE OR FALSE:

Letter A: Is an equilateral triangle An equilateral triangle has three sides and angles that are equal.

FALSE. A scalene triangle has NO sides or angles that are equal FALSE!!!!! A scalene triangle has NO sides or angles that are equal. An equilateral triangle has three sides and angles that are equal. SCALENE EQUILATERAL

The Answer is B: FIVE 4 3 5 2 1

Another name for a translation is a “step” TRUE OR FALSE? Another name for a translation is a “step”

FALSE!!!!!!! Another name for a translation is a SLIDE!! A translation is when you move a figure up, down, or over.

WHICH IS AN EXAMPLE OF A REFLECTION: B C

A: A reflection is when you FLIP an object over a line. Think of the object looking “opposite” or think of a “mirror effect.”

A radius of a circle is half the length of the diameter? TRUE OR FALSE: A radius of a circle is half the length of the diameter? B A

TRUE!!!!!!!! B A The radius is a line segment whose end points are the center of the circle and a point on the circle.

What is the name of the circle below? A: Circle MS B: Circle A C: Circle MSA

A circle is named by its center point. This is circle A B: Circle A A circle is named by its center point. This is circle A

Which circle shows the diameter? B A B B A A B C

Circle B shows the diameter The diameter of a circle is a line segment that goes trough the center of a circle and whose end points are on the circle.

If the radius of the circle is 2, how long would the diameter be?

The radius is half the length of the diameter so if the radius is 2, the diameter would be 4!!! C B A 2 2
