Lesson: Geometric Constructions: Triangles Mathematics • 7th Grade
In this lesson, we will learn how to construct a triangle given its three sides and use its properties to solve problems.
Draw a triangle in which , , and . Bisect with a line that intersects at the point . Measure the length of .
Draw a triangle in which and . First, bisect at and at , then connect the points to draw . Using the drawing, determine the length of
Draw the triangle , where , , and . Then draw a perpendicular line from to intersecting it at , and a perpendicular line from to intersecting it at . Use the ruler to find the lengths of and .
