Textbook Problem

Draw an obtuse triangle and, by construction, find its circumcenter.

To determine

**To draw:**

The obtuse triangle constructs its circumcenter.

Explanation

**Procedure used:**

**STEP 1:** We start with the obtuse triangle

**STEP 2: **Construct the bisector of the line segment

**STEP 3:** Again without changing the compasses width, place the compasses point on the other end of the line. Draw an arc above and below the line so that the arcs cross the first two.

**STEP 4:** Using a straightedge, draw a line between the points where the arcs intersect. This line is perpendicular to the first line and bisects it.

**STEP 5:** In the same manner, draw Construct the bisector of the line segment

**STEP 6:** The point where these two perpendiculars intersect is the obtuse triangle's circumcenter.

**Given:**

Draw a obtuse triangle. Construct its circumscribed circle.

**Clarification:**

**STEP 1:** We start with the obtuse triangle *A, B, C*.

**STEP 2: **Construct the bisector of the line segment
