Please be sure to answer the question.Provide details and share your research! Hint: Draw a right angle first. In Euclidean geometry, the base angles can not be obtuse (greater than 90°) or right (equal to 90°) because their measures would sum to at least 180°, the total of all angles in any Euclidean triangle. You can also draw a triangle with the polygon shape tool. First you draw the long base. Constructing an isosceles triangle when the apex angle and the lengths of the two equal sides are given. How to draw an isosceles triangle given the base and altitude with compass and straightedge or ruler. Sides b/2 and h are the legs and a hypotenuse.
