What is a triangle? What attributes must a shape have to be called a triangle?
A triangle is a three-sided shape with three points and three angles.

What are complementary angles? What are supplementary angles?
Complementary angles add up to equal 90 degrees. Supplementary angles add up to equal 180 degrees.

What is a quadrilateral? What does it mean for lines to be parallel? What does it mean for lines to be perpendicular?
Parallel lines are lines that do not touch and will never meet no matter how far you extend them. Perpendicular lines are lines that meet to make 90 degree angles. A quadrilateral is a four-sided shape.

3 quarter turns around a circle is how many degrees?
270 degrees.

Draw an equilateral triangle. Describe what makes it equilateral.
An equilateral triangle has three equal sides.
200
Opposite angles are __________ to one another. Draw a figure that proves this.
Opposite angles are equal to one another.

What is a trapezoid? How is different from a parallelogram?
A trapezoid has one set of parallel lines and a parallelogram has two sets of parallel lines.
200
Use 90 degrees and the terms less than, greater than, or equal to to describe acute, obtuse, and right angles.
Obtuse angles are greater than right angles, or 90 degrees. Acute angles are less than right angles, or 90 degrees. Right angles are equal to 90 degrees.
300
How many lines of symmetry are there on an equilateral triangle?
There are 3 lines of symmetry on an equilateral triangle.
300
How many degrees are in a straight line? If a straight line is divided into two parts (two angles), and one angle is 47 degrees, how many degrees is the other angle? What equation would you use to measure this angle?
180-47=Y, Y=133 degrees.

What is the difference between a rectangle and a square?
A square is a special type of rectangle. Rectangles and squares both have two sets of parallel lines and four right angles. A square also has four equal sides.

How would you describe a 180 degree turn around a circle?
A 180 degree turn around a circle would be half-way across the circle, two quarter turns, a straight line across the circle.
400
Draw an obtuse, isosceles triangle. Draw all possible lines of symmetry. Describe what makes it obtuse and what makes it isosceles.
An obtuse triangle has an obtuse angle and an isosceles triangle has two side lengths that are equal. An isosceles triangle has one line of symmetry.

How many degrees are in a full circle? If part of that circle is 81 degrees, how many degrees are in the other part? What equation represents this problem?
360-83 = C, C =279
400
What is a quadrilateral with four equal sides and no right angles? How many lines of symmetry?
Rhombus, two lines of symmetry.
400
How many one 90 degree turns are there in a circle?
Four 90 degree turns or right angles in a circle.
500
Draw a right, scalene triangle. Draw all possible lines of symmetry. Describe what makes it a right triangle and what makes it a scalene triangle.
A right triangle has one right angle in it and a scalene triangle has all unequal sides. With scalene triangles there are no lines of symmetry.
500
A right angle has a line segment cutting through it dividing it into two parts. One part measures 24 degrees. What does the other part measure? What equation would you use to represent this problem?
90-24=X, X= 66 degrees
500
What is a four sided figure with four right angles with a width of 4 cm and a length of 3 cm? How many lines of symmetry does it have?
A rectangle and it has two lines of symmetry.
500
What is a degree? How would you describe a degree as a fraction?
A degree is the unit of measure for angles, as a fraction a degree is 1 turn of 360 total turns, or 1/360.
