![]() This is a bit more complicated because it requires us to use several constructions that we have done before. What if we are given a triangle and want to construct another triangle congruent to it? This means that the triangles DAB, CAB, and EAB are all right triangles. In the figure shown, the lines AD and BC are perpendicular. We can then connect any two points on these lines with a straightedge to get a right triangle. Therefore, to construct a right triangle, we have to construct a line perpendicular to another line. If we have a right triangle, this means that two of the legs of the triangle are perpendicular. Note that no triangle can have more than one right angle or obtuse angle. ![]() Right triangles have a right angle, obtuse triangles have one angle greater than a right angle, and acute triangles have all three angles less than a right angle. We can classify these figures by the relationship between the lengths of their sides and by the angles the sides form.Įquilateral triangles have three sides of equal length, isosceles triangles have exactly two sides of equal length, and scalene triangles have no sides of equal length. Construction methods can also help us to classify triangles.Īny time we draw a figure enclosed by three straight sides, we construct a triangle. Problems involving the construction of triangles include constructing triangles with a giver vertex, a given segment, or three given segments. We have already discussed how to make an equilateral triangle, and we will use this skill to help us make some of the other types of triangles. It is possible to construct equilateral triangles, isosceles triangles, scalene triangles, acute triangles, obtuse triangles, and right triangles using only a compass and straightedge. ![]() Construct a Triangle – Explanation and Examples ![]()
