Jun 5, 2023 · Compute the sum of squares of the two smaller sides. Compare it to the square of the longest side . If the sum is greater, your triangle is acute. If they are equal, your triangle is right. If the sum is shorter, your triangle is obtuse. This method is based on the law of cosines. That means that side c c c is perpendicular to the bases, and therefore equal to the height c = h c = h c = h. However, we don't know c c c, so we'll have to find it still. To do this, draw the height of our trapezoid that goes from the vertex between b b b and d d d. Together with d d d and a part of a a a, it forms a right triangle.The angle between two sides can be anything from greater than 0 to less than 180 degrees. The angle between two sides can't be 0 or 180 degrees, because the triangle would then become three straight lines superimposed on each other (These are called degenerate triangles). Similar triangles have the same angles, but different length sides.Named after the ancient Greek mathematician Pythagoras, this theorem states that: in a right-angled triangle, the square of the hypotenuse is equal to the sum of squares of other two sides.
