adjacent angles
2 angles who share a common vertex and a common side
180 degrees
which value ALWAYS goes in the first fraction?
the scale
the flat surfaces on a 3D figure
faces
formula used to solve for complementary angles
angle + angle = 90
vertical angles
2 angles formed by intersecting lines that are opposite each other & congruent
what formula do you use to determine if 3 given side lengths will form a triangle?
small + small > big
labels on both sides of a scale drawing problem will be across/opposite each other (choose either across or opposite to answer this question)
across
the places where 2 faces meet (the lines)
edges
formula used to solve for supplementary angles
angle + angle = 180
complementary angles
two angles whose sum is 90 degrees
when you're given 2 sides of a triangle what do you do to find the range of values that could make up the third side?
find the sum and difference of the given side lengths
once you have set up your fractions, how do you begin to solve the problem?
cross multiply
the place where 2 edges meet (the points)
vertex, corner
formula used to solve for vertical angles
angle = angle
supplementary angles
2 angles whose sum is 180 degrees
angles and side lengths of triangles are connected. for example, the largest angle is across from the _________ side
largest
I am going on a trip to Nashville, TN. On my map, 3 centimeters represent 75 miles. Nashville is 8 centimeters away on the map. What is the scale in this problem?
3 cm : 75 miles
when a figure is cut horizontally, the resulting shape will always match the _______
base
formula used to solve for a missing angle when there are three angles that form a line
angle + angle + angle = 180
name the four angle types we discussed in class (hint: we had arm motions for them)
acute, obtuse, right, straight
name the four types of triangles we discussed in class
right, isosceles, scalene, equilateral
I am going on a trip to Nashville, TN. On my map, 3 centimeters represent 75 miles. Nashville is 8 centimeters away on the map. What are possible labels for the top and bottom of my fraction for this problem?
map / real life
a triangular prism has what shape for a base?
triangle
formula used when solving for a missing angle when two adjacent angles don't add up to 90 or 180
angle + angle = angle
