Right angle : 90 degrees :: __________ angle : 180 degrees
a. acute
b. right
c. straight
d. obtuse
Suppose that ā, 5, and ē are vectors in R2 such that the angles between (a, b) and (ā, 2) are both oblique (i.e., between 0 and 90°). Then the angle between (a, a) where d=5+ Čis: a. Oblique, 0º < 0 < 90° b. Right, 0 = 90° c. Obtuse, 90° <O< 180° d. Straight, 0 = 180° e. Cannot be determined on the basis of the information given.

Activity 7: Right or Not? Develop or reinforce the Pythagorean theorem and its converse and explore the relationship between the lengths of the sides of a triangle and its classification as acute, right, or obtuse Online: Centimeter Graph Paper Other: Scissors PURPOSE MATERIALS Work individually or in pairs. GROUPING From a sheet of graph paper, cut out squares with areas 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, and 169 square centimeters. Use three squares to construct a...
8.4 Which of the following is not true? Choose the correct answer. A. We verify an identity by trying to transform one side of the identity into the exact trigonometric expression that appears on the opposite side. B. If one side of an identity includes a trigonometric expression involving the sum or difference of sine and cosine or the product of sines and/or cosines, then to verify the identity always start by transforming the other side of the identity. C....
