Adjacent
Which polygon has two lines of symmetry and has all equal angles measured at 90 degrees?
What is a rectangle?
This angle looks like the tip of a triangle and measures less than 90 degrees.
What is an acute angle?
Which angle is less than 90 degrees?
It's called an acute.

Name three polygons that have ONLY one line of symmetry.
What are kite, isosceles trapezoid, and isosceles triangle?
These three angles, in order, are found to be across from each other and congruent, form the letter pattern z, and form the letter pattern c.
What are opposite/vertical, alternate, and co-interior angles
Name all the angles.
Acute, Obtuse, Right angle, and straight.
A quadrilateral has three measures given.
<60 + <90 + <120
What is the fourth angle measure? Is it possible to make the quadrilateral?
What is 90 degrees and yes it is possible as the neighbouring angles add up to 180 degrees?
What are the lines that meet at a 90 degree angle?
What are perpendicular lines?
