Which figure has two acute and two obtuse angles?

A trapazoid. If the base (Side AB) was 6 cm and the top (Side CD) was 3 cm, then angles A and B would be acute, angles C and D obtuse.

What are the lower and upper base angles in a trapezoid?

In a trapezoid, the lower base angles are the angles formed between the base and the legs of the trapezoid on the bottom side, while the upper base angles are those on the top side. For an isosceles trapezoid, the lower base angles are congruent to each other, as are the upper base angles. The sum of the lower and upper base angles equals 360 degrees, with each pair of adjacent angles summing to 180 degrees.


What is the side of a triangle that is a side of each of two angles?

Every side of any triangle is a side of each of two angles. In fact, every side of every polygon is a side of each of two angles.


In an isosceles triangle are the base angles the biggest?

The two base angles are equal to one another. They may either be the two smallest, or the two largest, angles.


What two pairs of angles formed are base angles?

What relationships exist between the two congruent sides of an isosceles triangle and its base?

The angles where the equal sides meet the third side of the triangle are equal angles.


How can you find the height of a triangle if you only have the base?

You can't! If the base is the only side you know, you'll need two angles to define the triangle entirely
