Topic 5 Flashcard Review

Front

Do the following side lengths form a triangle? 2 inches, 2 inches, 4 inches

Back

No, these lengths do not satisfy the triangle inequality theorem.

Front

Identify the smallest angle in a triangle with angles ∠A, ∠B, ∠C.

Back

∠A is the smallest angle.

Front

What type of center is point M in a triangle?

Back

Point M is the Incenter.

Front

The INCENTER is the intersection of which special segments?

Back

Angle Bisectors.

Front

The altitudes of a triangle intersect at the _________________________.

Back

Orthocenter.

Front

What is the Triangle Inequality Theorem?

Back

The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Front

Define the term 'Incenter'.

Back

The Incenter is the point where the angle bisectors of a triangle intersect.

Front

What is the purpose of the Circumcenter?

Back

The Circumcenter is the point where the perpendicular bisectors of the sides of a triangle intersect, and it is equidistant from the vertices.

Front

What is the difference between the Centroid and the Orthocenter?

Back

The Centroid is the intersection of the medians of a triangle, while the Orthocenter is the intersection of the altitudes.

Front

How do you find the area of a triangle using its base and height?

Back

Area = 1/2 * base * height.
