What is SUPPLEMENTARY?
200
Angles that are equal to 180 degrees
What is straight angles?
200
Triangles that have no equal sides
What is scalene triangles?
200
What is the measure of each interior angle of an equilateral triangle?
What is 60 degrees?
200
A triangle has a 90° angle, a 60° angle, and one 6-centimeter side. How many unique triangles can be made?
More than 1!
Because they did not describe the placement of the angle
200
write an equation to express this relationship
105= 5x+110
or
5x+ 110=105
Vertical angles
300
Angles that are equal to 90 degrees
What is right angles?
300
Triangles that have two equal sides
What is isosceles triangles?
300
Two interior angle measures of a triangle are 74 degrees and 53 degrees. What is the measure of the third interior angle?
What is 53 degrees?
300
One 4-centimeter side, one 6-centimeter side, and one 50° angle. How many non-identical triangles can be made using these measurements
More than one triangle because there is no specific placement of the angle
300
If given 3 side lengths how many unique triangles can be made?
only 1 Unique triangle
400
Angles that are greater than 90 degrees but less than 180 degrees
What is obtuse angles?
400
Triangles that have three angles less than 90 degrees
What is acute triangles?
400
Can a triangle have these interior angle measures? Why or why not? 36.9 degrees, 110.4 degrees, and 33.7 degrees
What is no, they do not have a sum of 180 degrees?
400
A triangle has a 90° angle, a 60° angle, and one 6-centimeter side. Is there a complementary relationship?
The triangle contains two angles that are complementary because the 90 degree angle means that the sum of the other 2 must be 180 degrees total.
400
If given 3 angles how many unique triangles can be made?
We can make more than one (infinite number) of triangles that are larger or smaller but have the same angles. (Scale copies)
500
Total number of degrees in a triangle
What is 180 degrees?
500
Triangles that have one angle greater than 90 degrees

600
Triangles that have one 90 degree angle?
What is a right triangle?
600
The interior angles of a triangle are "x" degrees, "x + 70" degrees and 28 degrees. Find the value of x.
What is 41 degrees?
600
How many non-identical triangles can be made using these side lengths? 6 centimeters, 10 centimeters, 16 centimeters
