What is an acute angle?
What is an equilateral triangle?
How many 90 degree rotations are in 360?
4
See Picture 2
What type of angle is shown?
An acute angle
Has eight sides
What is an octagon?
What is an obtuse angle?
Has 2 equal sides
What is an isosceles triangle?
Name the 4 angle rotations in a circle.
90, 180, 270, 360
Choose one person to measure the angle in picture 3
120 degrees
This polygon has 4 sides
What is a quadrilateral?
Draw a figure with a right angle.
Draw an obtuse triangle.
See Teacher
If an angle rotated 27 degrees, what fraction represents that angle?
27/360
Choose one person to draw an angle of 82 degrees
Teacher will check
How many lines of symmetry does it have?
What is 2?
180 degrees
What is a straight angle?
Why can a triangle only have one obtuse angle or one right angle?
It is not possible to connect the sides to make a triangle if two or more angles were right or obtuse.
Mrs. Miller's class had ELA from 9:00 am. The minute hand moved 270 degrees. What time did Mrs. Miller's class end ELA?
9:45 am
See picture 4
<BHC= 73
Has infinite lines of symmetry
What is a circle?
See picture 1
What is <ABC = 110
What is <FBE = 45
What do we know about the angles in an equilateral, scalene, and isosceles triangle?
We know that all of the angles are equal because the sides are equal in an equilateral triangle.
We know that two angles are equal in an isosceles triangle.
We know that none of the angles are equal in a scalene triangle.
A sign rotated 72 degrees. Then stopped. After 30 minutes, it rotated 108 degrees. What is the fraction that the sign rotated?
The sign rotated 180/360 or 1/2
See Picture 5
160 degrees
