If two sides and the included angle of the first triangle are congruent to the corresponding parts of the second triangle, then the correspondence is a congruence. A16 The Parallel Postulate: Through a given external point there is at most one line parallel to a given line.
In part 1, classify the following triangles according to ...
The triangle on the right is an equilateral triangle, in which all three sides and angles are equal. The vertical line is an altitude, meeting the side in a right angle. Using this information, but with no knowledge of what the numerical lengths of the side or altitude are, find the sine and cosine of the angle at B.

Triangle Sides and Angles - Texas Instruments
Now we will use trigonometry to find a missing side or angle when given a side and an angle or when given two sides of a right triangle. We will need to develop three trigonometric ratios: sine, cosine, and tangent, which are abbreviated sin, cos, and tan. Look at the diagram at the right. If we use angle A as our reference angle, then we can ...
