Can adjacent angles be complementary?
yes because two angles next to each other can sum to 90 degrees.
Angles that add up to 90 degrees are called
Complementary angles
A triangle that has all sides the same length is called
equilateral triangle
a 3d shape with the base the same as the top.
a prism
Can vertical angles be supplementary?
yes because angles across from each other can sum to 180, like two 90 degree angles.
Angles that add up to 180 are called
Supplementary angles
Which of these is a unique polygon?
A triangle with angles 30, 50, and 100
A triangle with side lengths 4, 5, 6
A triangle with side lengths 4, 5, 6
What is this
v = (area of the base) * (height)
Volume for a prism
Can complementary angles be supplementary?
no because it is impossible to add up to 90 and 180 at the same time.
an angle that is greater than 90 degrees
obtuse
A triangle has one angle of 30 degrees, another of 100 degrees, and a final angle that is called x. What is the measurement of x?
50 degrees
The revealed shape created when we slice a prism
a cross section
Is it possible to make a triangle with angle measures 30 and 60 and a 3cm side length?
yes because the 3cm side length can be between the two angle measures.
this is the number of degrees in a straight angle
180 degrees
A triangle with a 90 degree angle has two other unique angles called X and Y. What can X and Y NOT be?
They cannot be 45 degrees or any angles that add up to more than 90.
Is a square pyramid a prism? Why?
No because the base is not the same as the top
Is it possible to have a triangle with side lengths of 4, 5, and 19?
No because the sides are too short to connect from 19.
Angles A and B are supplementary. If angle A is 20 degrees, what is angle B?
60 degrees
All angles in every triangle will add up to this number of degrees
180 degrees
Given a prism, how do you know which side the base is?
The base is the same as the top. Sometimes we need to rotate or flip the ship over to find a base the same as a top.
A triangle has three angles. Two of the angles are complementary. What does the third angle have to be?
90 degrees, right angle
