Two angles with equal measurements are called congruent angles.
if two angles are supplements of the same angle (or of congruent angles), then the two angles are congruent.
Yes, an obtuse triangle can have two congruent angles, where for the obtuse angle measuring A degrees, each of the two other angles measures (180-A)/2.
Two angles that are congruent have the same angle measurement.
The base angles of an isosceles triangle are congruent. The vertex angle of an isosceles triangle is not necessarily congruent to the base angles.
angle bisectorangles bisector is the line that divides an angle into two congruent angles.
A line that bisects an angle into two different congruent angles is called an angle bisector.
Both are used to prove triangles congruent. ASA means there are 2 sets of corresponding congruent angles with 1 set of congruent sides between them. AAS means there are 2 sets of corresponding congruent angles and 1 set of congruent sides that is not between the angles.
Each of the base angles measure 71 degrees
It depends on what is given.In general, one half of the bisected angle is proven to congruent to the other half. By the Definition of an Angle Bisector, the bisected angle can be proven bisected.---- To show that two angles are congruent:One way to prove the two angles congruent is to show that their measures are equal. This can be done if there are numbers on the diagram. Use the Protractor Postulate or the Angle Addition Postulate to find the smaller angles' measures, if they are not directly marked. Then use the Definition of Congruent Angles to prove them congruent.Given that the smaller angles correspond on a congruent or similar pair of figures in that plane and form an angle bisector, the Corresponding Parts of Congruent Figures Postulate or Corresponding Parts of Simlar Figures Postulate may be used.
Angle Angle Side is a method one can use to prove that two triangles are congruent. Basically, if any two pairs of angles and the side between these angles are congruent, then the triangles are congruent as well.
An Angle Bisector
Dividing the angle into 2 congruent angles
Congruent angles (or equivalent angles) have the same angle measure.
Yes. The lower base angles are congruent. The upper base angles are congruent.
No. An angle can have only one angle!
Without a visual or more information, I'm guessing that the picture is of angles 1 and 2 that are consecutive (share an angle side) and a separate picture of consecutive angles 3 and 4. With that said: 1) angle 2 congruent to angle 3................1) given 2) angle 1 is supplementary to angle 2....2) If angles are next to each other --> supps angle 3 is supplementary to angle 4 3) angle 1 congruent angle 4..............3) If supps to congruents angles ---> congruent
Yes. The side lengths for angle measures don't count.
Yes. Angles are congruent if they have the same measure.
No, they cannot, because if you think about it, the sides can be different proportional lengths but have the same angle measures.
When all of their corresponding angles are congruent (in any triangle, in fact) then the triangles are similar. Similarity postulate AAA. (angle-angle-angle)
There are only 4 possible numbers which could be measures of the angles for the quadrilateral. Each of the infinitely many other measures, such as 36.57 degrees, could NOT be the measure.
A single angle can only add up to its own value! And how can a single angle be congruent? There have to be at least two angles for them to be congruent (or not).
If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent.
