https://info.5y1.org/sides-of-a-triangle-calculator_1_f7e4d3.html
If the triangle is obtuse they will meet at a point outside of the triangle. If the triangle is a right triangle they will meet at a point on the hypotenuse. 3 points. Now we will explore a characteristic of the point of concurrency of the angle bisectors of a triangle. Let’s go back to our triangle in the calculator.

A useful trick to check how a calculator works: For a right triangle with an angle of 45(, the tangent ratio is equal to exactly one because the two acute angles are equal (both 45(), resulting in two equal sides.

The triangle on the right is an equilateral triangle, in which all three sides and angles are equal. The vertical line is an altitude, meeting the side in a right angle. Using this information, but with no knowledge of what the numerical lengths of the side or altitude are, find the sine and cosine of the angle at B.

In this activity we will explore what happens when we construct the three perpendicular bisectors of the sides of an acute triangle, a right triangle, and an obtuse triangle. Before you begin, you must make sure your calculator is in degree mode and not in radian mode. Do this by pressing the home key and selecting . 8: System Info, then
