Q: What fraction of the figure is shaded?

(4) 8/12. The figure is divided into 12 equal sectors. 8 of these sectors are shaded. Therefore, the fraction of the figure that is shaded is 8/12.

Q: Which one of these shapes has a right angle in it?

(2) 2. A right angle measures 90 degrees. Shape (2) is a right trapezoid, which clearly contains right angles, indicated by the square symbol at its bottom-left corner.

Q: Look at the angle marked on each letter. Which letter is marked with an obtuse angle?

(3) V. An obtuse angle is greater than 90 degrees and less than 180 degrees. - The angle marked in H is a right angle (90 degrees). - The angle marked in M is an acute angle (less than 90 degrees). - The angle marked in V is an obtuse angle (greater than 90 degrees). - The angle marked in X is an acute angle (less than 90 degrees).

Q: How many acute angles are there in the shape below?

(1) 1. An acute angle is an angle less than 90 degrees. Examining the pentagon: - The bottom left angle is clearly acute. - The bottom right angle is a right angle. - The top right angle is obtuse. - The top angle is obtuse. - The top left angle is obtuse. Thus, there is only 1 acute angle.

Q: Which of these fractions is greater than 4/5?

(4) 6/7. To compare, convert all fractions to decimals: 4/5 = 0.8 (1) 2/3 ≈ 0.667 (2) 5/8 = 0.625 (3) 7/10 = 0.7 (4) 6/7 ≈ 0.857 Only 6/7 is greater than 0.8.

Q: Look at the figure below. Which of the following is correct? (1) AB // CD (2) AD // BC (3) AB ⊥ DC (4) DC ⊥ BC

(2) AD // BC. The square symbols at vertices A and B indicate that AB is perpendicular to AD (AB ⊥ AD) and AB is perpendicular to BC (AB ⊥ BC). If two lines are both perpendicular to a third common line, then they must be parallel to each other. Therefore, AD // BC.
