Two isosceles triangles are similar, if the angle between their:
Correct answer: D. None of these
- A. Unequal arms are equal
- B. Equal arms are equal
- C. Unequal arms are unequal
- D. None of these
Explanation
Option D is correct.Two isosceles triangles are similar if an angle of one is congruent to the corresponding angle of the other.No, two isosceles triangles are not similar if the angle between their equal arms are equal. Similar triangles are two triangles that have the same shape, but not necessarily the same size. For two isosceles triangles to be similar, the following conditions must be met: 1,The two triangles must have equal angles at their vertices. 2.The sides that are opposite the equal angles must be in proportion.

About Simple Harmonic Motion
Simple harmonic motion is oscillation in which acceleration is directly proportional to displacement and directed toward the equilibrium position. Work includes displacement, velocity, acceleration, phase, period, frequency, amplitude and energy, with applications to springs and simple pendulums. The restoring force and the conditions for SHM distinguish it from general periodic motion.
