Final answer:
Two triangles are congruent if their corresponding sides and corresponding angles are congruent, therefore, the statement is true. However, knowing only the angles of two vectors does not allow us to find the angle of their resultant; additional information about magnitudes is required. Pythagorean theorem applies when vectors are at right angles to each other.
Step-by-step explanation:
True or False-If only the angles of two vectors are known, we can find the angle of their resultant addition vector.
a. False
60. True or False-A vector can form the shape of a right angle triangle with its x and y components.
a. True
83. True or False-If only the angles of two vectors are known, we can find the angle of their resultant addition vector.
a. False
36. True or False-We can use Pythagorean theorem to calculate the length of the resultant vector obtained from the addition of two vectors which are at right angles to each other.
a. True
58. Is this statement true or false? The amplitude of one wave is affected by the amplitude of another wave only when they are precisely aligned.
a. True
84. True or false-We can find the magnitude and direction of the resultant vector if we know the angles of two vectors and the magnitude of one.
a. True
Two triangles are congruent if and only if their corresponding sides and corresponding angles are congruent. This statement is True
