Why can we assume that <FDE and <BDE are congruent?
Because they are vertical angles.
2 angles that add to 90 degrees.
What is a complementary angle?
sqrt[(x-x)^2+(y-y)^2
The name of the formula above.
What is the distance formula
Is the following three-dimensional shape a polyhedron? If so, how many faces does it have?
What is YES and 5 faces.
Reflect the following points over the y-axis
A(-2,2)
B(3,-6)
C(4,4)
A'(2,2)
B'(-3,-6)
C'(-4,4)
Can we assume that <4 and <6 are complementary?
No, because they are supplementary.
2 angles that add to 180 degrees.
What is a supplementary angle?
The result of adding all of a shapes sides together.
What is the perimeter?
Is the following image a polyhedron? If so, how many faces does it have?
What is NO?
Reflect the following points over the x-axis.
P(-3,5)
Q(9,10)
R(4,-7)
P(-3,-5)
Q(9,-10)
R(4,7)
Can we assume that DC is perpendicular to AC?
No, because they don't show that angle ACD is a right angle.
2 nonadjacent angles that have a common endpoint.
What is a vertical angle?
Find the area of a square that has a side composing of the points (-1,2) and (-3, 5)
What is 26.
