What are mid-segments?
A midsegment of a triangle is a segment connecting the midpoints of two sides of a triangle.

If we reflect (a,b) about the X axis, what would it be reflected to?
Then it is reflected to the 4th quadrant (a,-b).

What is a plane?
Plane (geometry) In mathematics, a plane is a flat, two-dimensional surface that extends infinitely far.

Write the conditional to this statement: A rectangle has four sides.
If it is a rectangle, then it is an animal.

How can you tell the difference between a parallel and perpendicular line?
Parallel lines are always the same distance a part and never touching. Perpendicular just means there are right angles and the bottom line is connected to the line going straight up.

When three or more lines intersect in one point, they are......
Concurrent

If there is an image in the 4th quadrant, what quadrant would the rotation of 180 degrees be?
It would be in the second quadrant.

If the radius of a circle is 6, what is the circumference?
37.68

Write the two statements that form each biconditional: A line bisects a segment if and only if the line intersects the segment only at its midpoint.
A line bisects a segment, the line intersects the segment only at its midpoint.

What is theorem 3-10 to parallel and perpendicular lines?
If 2 lines are perpendicular to the same line, then these 2 lines are parallel to each other.

Why can't SSA prove triangles are congruent?
If two triangles are initially congruent, there can be another triangle that just got cut off the triangle that is congruent to the other one so it isn't congruent anymore to the other triangle but it still satisfies SSA.

If you start out in quadrant 1 what quadrant would you be in after a reflection?
Quadrant 4

Find the area of an acute triangle with a base of 15 inches and a height of 4 inches.
A = 1/2 · (15 in) · (4 in)
A = 1/2· (60 in2)
A = 30 in2

What is the conditional statement to this statement and is it true? Lines m and n are skew if and only if m and n do not intersect.
It is true and the conditional is.. If lines m and n are skew, then m and n do not intersect.

What postulate is when a triangle shows all the sides congruent to each other?
SSS (side-side-side).
