Angles 101
An angle that measures 90 degrees
Right Angle
Angles where no matter how you move the transversal, the angles will always be congruent (equal).
Corresponding Angles
Two angles that combine to create a right angle
Complementary Angle
What is the measure of the angle that has a complement of 81 degrees?
9 degrees
What is Ms. Silfrene's first name?
Judith
An angle that is less than 90 degree
Acute angle
Interior angles are angles located
Inside the parallel lines
Two angles that combine to create a straight line
Supplementary angle
What is the measure of an angle that has a supplement of 139 degrees?
41 degrees
How many times did Mr. Farrell sit on a jury?
One time but he was called twice.
An obtuse angle measures
greater than 90 degrees
Angles that are opposite each other and inside the parallel lines are called
Alternate Interior Angles
Angles that are side by side and share the same line
Adjacent Angles
Vertical angles are not congruent
False
How many children does Mr. Awad have?
Three
A straight line equals
180 degrees
DOUBLE JEOPARDY!!
Name the angles that are outside the parallel lines and on opposite sides.
Alternate Exterior Angles
Angles that are equal to each other and opposite of one another
Vertical Angles
In a straight line, the m<1=9x+24, m<2=3x+12. What is the measure of <2?
m<2 =48
What after school activity does Mr. Awad help lead?
Mock Trial
Square corners are created by
Perpendicular lines
In the handout from yesterday, <3 and <6 were on the same side of the transversal. <1 and <8 are also on the same side of the transversal. So we call them..
Same side interior angles & same side exterior angles.
Three criteria that must be met for two angles to be a linear pair
Adjacent angles, equal 180, and fall on the same line.
<1 and <2 are a linear pair. If <1=13x-15 and m<2=6x+5, find x, m<1, and m<2
x=10, m<1=115, m<2=65
How long has Ms. Silfrene been a teacher?
