Tofind:The whether each statement is always, sometimes, or never true.

Answer to Problem 27SGR
Thestatement is sometimestrue.
Explanation of Solution
Given information:The given information is:If two
Calculation:
Let consider the statement.
If two angles are complementary, then they form a right angle.
Now,
If two angles are vertical angles they equal
Sometimes, if the angles are adjacent they will be complementary.
Therefore, the statement is sometimes true.

Mary reasoned that she could draw a rectangle around the figure so that the point O was at a vertex of the rectangle and that points A and B were on sides of the rectangle. Then she reasoned that the three smaller triangles resulting could be subtracted from the area of the rectangle. Mary determined that she would need 28 square meters of artificial turf to cover the green shaded yard space pictured exactly.arrow_forward
