What are base angles?
Either of the two angles of a triangle that has the base for a side.
What angles of an isosceles trapezoid are congruent?
The pair of angles at the end of each parallel side - the two base angles and the two top angles - are congruent.
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.
Two angles that share a base of a trapezoid?
Base angles.
The two angles that include the base of an isosceles triangle?
Base Angles
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?
They would probably be the two pairs of angles in the parallelogram or kite base of a quadrilateral based.
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
Which two angles of isosceles triangle is congruent?
The two base angles are equal
How do you find the height of a triangle if you only have the base?
You cannot. You need further information: two angles, or two sides, or one of the base angles and a side. There are other possibilities involving perpendicular bisectors, or medians etc but then the maths can become rather complicated.
