Prove: height “h” splits the triangle into two triangles. they are both right-angled triangles and they share an acute angle with the big triangle. so their angles are equal to the big triangle ones. so the small triangles are similar to the big triangle. so their ratios of the hypothenuse and one short side are equal: and . The Pythagoras ...

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.
