Side Lengths
Will the side lengths of 2cm, 3cm, and 10 cm make a triangle?
What is no. The short sides will not add up to a total greater than the long side.
Is a triangle with angle measures of 20, 100, and 50 degrees possible?
What is no.
A triangle must equal 180 degrees total.
Are 40 and 50 degree angles complementary?
What is yes. They add together to equal 90 degrees.
Are 110 and 70 supplementary angles?
What is yes. They add together to equal 180 degrees.
Correctly draw a 70 degree angle.
Check Student's work.
Will the side lengths of 5cm, 8cm, and 4cm make a triangle?
What is yes. The short sides add up to a total greater than the long side.
A triangle has angle measures of 45 and 45 degrees.
What will the third angle equal?
What is 90 degrees.
Are 35 and 125 degree angles complementary?
What is no. They do not add together to equal 90 degrees.
Are 120 and 61 degree angles supplementary?
What is no. They do not add together to equal 180 degrees.
Suppose the measure of one angle is 90 degrees and the other is 45 degrees.
Draw these two angle adjacent (sides are touching) to each other.
Check Student's work.
Will the side lengths of 5cm, 5cm, and 3cm make a triangle?
What is yes. The short sides add up to a total greater than the long side.
What will the total internal angles of a quadrilateral equal?
What is 360 degrees.
Complementary angles pair together to create what total angle?
What is 90 degrees.
Supplementary angles pair together to create what total angle?
What is 180 degrees.
If an angle measure is 20 degrees.
What is the supplement to this angle?
Draw the supplementary angles.
Check Student's work.
The supplement is 160 degrees.
A triangle has side lengths of 5cm and 7 cm.
The measure of the longest side is missing.
What is the longest length this side could be?
What is 11 cm.
Is a triangle with angle measures of 100, 35, and 45 degrees possible?
What is yes.
A triangle must total 180 degrees.
Are 100 and 80 degree angles complementary?
What is no. They do not add together to equal 90 degrees.
If you have an angle measure of 135, what is the supplement to this angle?
What is 45 degrees.
If an angle measure is 25 degrees.
What is the complement to this angle?
Draw the complementary angles.
Check student's work.
The complement is 65 degrees.
Will side lengths of 12cm, 13cm, and 25cm make a triangle?
What is no. The short sides will not add up to a total greater than the long side.
Is a quadrilateral with degrees 60, 120, 60 and 120 possible?
What is yes.
Quadrilaterals must equal 360 degrees.
If you have an angle of 30 degrees, which is the complement to this angle?
What is 60 degrees.
What is the measure of the supplement to the angle of 25 degrees?
What is 155 degrees.
Draw a triangle with side AB= 6cm, BC= 5cm, and angle ABC= 50 degrees.
