What kind of triangle is this (angle name)?
What is an Obtuse triangle?
Define quadrilateral.

4 - FC, BC, DC, GC

This angle is:

What is acute?
How many lines of symmetry in an isosceles triangle?
1
A triangle has how many degrees in total.
What is 180?

Name this quadrilateral.
What is a parallelogram?
Name this kind of line:

What are perpendicular lines?
These angles are supplementary or complementary?

What is complementary?
Find the perimeter.

8 + 8 + 10 +10 + 7 = 43 cm
Name the three kinds of triangles when talking about their side lengths.
What is scalene, isosceles and equilateral?
Name a quadrilateral with two pairs of parallel sides and 2 pairs of opposite congruent sides.
What is a rectangle or a square?

Name the lines that are parallel in this image.
What is line CE and line FH?

What is acute equilateral?
Name the quadrilateral that has only one pair of parallel lines.
What is a trapezoid?

The following type of line is called what?

What is a ray? (A line that has a vertex or point at one end and continues forever in the other direction)

Determine angle measure x.
What is 62 degrees?

10
Find the missing angle measurement in this triangle:

What is 65 degrees?
Name 5 quadrilaterals.
Rectangle, parallelogram, trapezoid, square, rhombus. (Kite would also work - but we didn't touch on kites much).
Are these two lines intersecting? (Might be a trick question....)

YES - because they don't have a vertex meaning that if you continued them, they would touch eventually.
Is this a pair of supplementary angles? Why or why not?
Yes - supplementary angles add up to 180. They don't have to be touching to be a pair of supplementary angles.
A rectangle has an area of 48 cm2 . What are two combinations of side lengths that would give this area?
8 and 6; 24 and 2; 4 and 12; 3 and 16
