Create an Isosceles Triangle
1) From point P, use the Circle with Center through Point tool
to create a circle centered at point P that intersects the dotted line in two place.
2) Use the Intersect tool
to mark the points where the circle intersects the dotted line.
3) Use the Polygon tool
to create a triangle with vertices at the three points shown.
4) Use the Distance tool
and the Angle Measure tool
to verify that the triangle is isosceles.
