Classify the triangle but it's angles and it's sides. Explain how you knew which classification to use.

70,8,65,12,45,11

This triangle is an obtuse triangle. This is because it has one angle that is greater than 90 degrees, which is the 70 degree angle. The other two angles are 65 and 45 degrees, which are both less than 90 degrees. The sides of the triangle are 8, 12, and 11.

Did you know?

Did you know that triangles can be classified based on their angles and sides? By examining the given measurements of 70, 8, 65, 12, 45, and 11, we can determine the triangle's classification. Firstly, let's consider the angles. If all angles are less than 90 degrees, it is an acute triangle. If one angle is exactly 90 degrees, it is a right triangle. Lastly, if one angle exceeds 90 degrees, it is an obtuse triangle. Next, we can evaluate the sides. If all sides are the same length, it is an equilateral triangle. If two sides are equal, it is an isosceles triangle. Finally, if all sides have different lengths, it is a scalene triangle. By analyzing the given measurements, we can apply these classification rules to determine the type of triangle.
