COMPASS Geometry 2

Question 1

What is the slope of a horizontal line?

Accepted Answer

0

Answer

A horizontal line has no vertical change (rise = 0), so slope = rise/run = 0.

Question 2

The midpoint of a segment with endpoints (2, 4) and (8, 10) is:

Accepted Answer

(5, 7)

Answer

Midpoint = ((2+8)/2, (4+10)/2) = (10/2, 14/2) = (5, 7).

Question 3

Two vertical angles are formed when two lines intersect. If one angle measures 65°, the vertical angle measures:

Accepted Answer

65°

Answer

Vertical angles are always congruent, so both measure 65°.

Question 4

What is the distance between the points (0, 0) and (3, 4)?

Accepted Answer

5

Answer

Distance = √(3² + 4²) = √(9 + 16) = √25 = 5.

Question 5

A circle has the equation x² + y² = 25. What is its radius?

Accepted Answer

5

Answer

In the standard form x² + y² = r², we have r² = 25, so r = √25 = 5.
