Atriangle has side lengths of 8 cm, 9 cm, and 14 cm. classify it as acute, obtuse, or right.

The correct answer is:

It is an obtuse triangle.

Explanation:

We use the Pythagorean Theorem to determine what type of triangle we have, based on the side lengths.

If a² + b² = c², the triangle is a right triangle.

If a² + b² < c², the triangle is an obtuse triangle.

If a² + b² > c², the triangle is an acute triangle.

Using 8 for a, 9 for b and 14 for c, we have:

8² + 9² and 14²

8² + 9² = 64+81 = 145

14² = 196

145 < 196; therefore a² + b² < c², and the triangle is obtuse.

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
