B: Point.Problem 4. Which of these statements is true? A: To know whether 2 triangles are similar, it is enough to know the measure of 1 angle. B: To know whether 2 triangles are similar, it is enough to know the length of 1 side. C: To know whether 2 triangles are similar, it is enough to know the measure of 2 angles in each triangle. D:Using the right triangle table we can estimate angle measures as in previous lessons. However, with a calculator, we can find angles more precisely. The side opposite angle A is 3 units long, and the side adjacent to A is 12 units long. So to find angle A, we write an equation using tangent: \tan (\alpha) = \frac {3} {12}.It emphasizes mathematical definitions and proofs as well as applicable methods.
