### TAKS Short Course Objective 3

6.6(A) The student is expected to use angle measurements to classify angles as acute, obtuse, or right;
3. The angle at each vertex of a regular octagon is 135°.

What type of angle is at each vertex of a regular octagon?

4. The table below shows different types of volcanoes and the angles formed by their slopes.

Based on the data in the table, which of the following statements is true about these volcanoes?

A) All the volcanoes have obtuse angles of slope.

B) All the volcanoes have acute angles of slope.

C) The cinder cone has an obtuse angle of slope, and the composite cone and shield have acute angles of slope.

D) The cinder cone has an acute angle of slope, and the composite cone and shield have obtuse angles of slope.

B) All the volcanoes have acute angles of slope.
• Acute angles less than 90 degrees and more than 0 degrees.
5. Look at the figure shown below.

Which of the following angles in the figure is obtuse?

A) NMR B) MRQ

C) PQR D) MNP

B) MRQ

Obtuse anglean angle that is more than 90 degrees less than 180 degrees.

6.6(B) The student is expected to identify relationships involving angles in triangles and quadrilaterals;
8. A triangle has angles measuring 45° and 55°. What is the measure of the triangle’s third angle?

9.Mr. Sosa has a ranch in the shape of a trapezoid. The sides of the ranch form angles measuring 60°, 80°, and 120°. What is the measure of the fourth angle?

10. RST shown below is an isosceles triangle. If the measure of R is 40°, what is the measure of S?

A 320° B 140°

C 70° D 40°

11. Look at the parallelogram shown below.

Which of the following could be the measures of the angles of the parallelogram?

A. 120°, 60°, 120°, 120°

B. 80°, 100°, 80°, 100°

C. 90°, 90°, 120°, 60°

D. 100°, 90°, 80°, 90°

A. 120°, 60°, 120°, 120°= 420°B. 80°, 100°, 80°, 100° = 360°C. 90°, 90°, 120°, 60° = 360°D. 100°, 90°, 80°, 90°= 360°
• 80°, 100°, 80°, 100° = 360°
• and opposite angles are congruent.
6.6(C) The student is expected to describe the relationship between radius, diameter, and circumference of a circle.

Which expression can be used to find the approximate circumference of the outer circle in centimeters?

A) π(3 + 8) B) (3 + 8)

C) 2π(3 + 8) D) 2(3 + 8)

13. A circle with center at point O is shown below.

Which line segment is 2 times the length of radius OK?

A Segment LN B Segment LM

C Segment LK D Segment ON

14. Rosa sliced an orange into circular pieces to put into a bowl of punch. The piece shown below had a radius of 4 centimeters.

Which expression can be used to find the approximate circumference of this piece of orange?

• 2(4) B)

C) D)

Which expression can be used to find the approximate circumference of this piece of orange?

D)

Circumference = diameter times Pi

15. Trevor knows the circumference of his bicycle tire, but he needs to find the diameter.

Which method can Trevor use to find the diameter?

A Multiply the circumference by 2 and divide the result by π

B Divide the circumference by 2 and multiply the result by π

C Multiply the circumference by π

D Divide the circumference by π

Circumference equals diameter times Pi

D) Divide the circumference by π
