Write the following words on your bingo card in a RANDOM order.

Answer each question and write a check mark in the box of your answer. The first person with 5 correct

answers in a row (horizontal, vertical, diagonal) wins!

Definition: A perpendicular segment from a vertex of a triangle to the opposite side, or to the line containing the opposite side.

Term: _________________

Three or more lines that intersect in one point are called __________________ lines.

The medians are concurrent at a point called the ___________________.

For a right triangle, the circumcenter is located ___________________ the triangle.

The altitudes of a scalene triangle ____________ intersect at a single point.

(Always, sometimes, or never?)

This point is equidistant from the vertices of a triangle.

These lines intersect at a point called the incenter.

The altitudes of a triangle are concurrent at a point called the __________________.

The angle bisectors _______________ intersect outside the triangle.

(Always, sometimes, or never?)

Given that the circumcenter of a given triangle lies inside the triangle, classify the triangle by its angles.

If a point is on the angle bisector of an angle, then it is equidistant from the _________ of the angle.

These lines intersect at a point called the circumcenter.

In an obtuse triangle, the orthocenter is located ____________ the triangle.

The incenter is equidistant from the _______________ of the triangle.

Is P on the angle bisector?

This segment connects the vertex of a triangle to the midpoint of the opposite side.

Given that the altitudes are concurrent at a vertex of the triangle, classify the triangle by its angles.

If a point is on the perpendicular bisector of a segment, then it is _________________ from the endpoints of the segment.
