Congruent angles are two or more angles that have the same measure. In simple words, they have the same number of degrees. It's important to note that the length of the angles' edges or the direction of the angles has no effect on their congruency. As long as their measure is equal, the angles are considered congruent.

Same side interior angles are on the same side of the transversal. Same side interior angles are congruent when lines are parallel.

Angles ABC and CDA are congruent according to a property of parallelograms (opposite angles congruent). Angles BAC and DCA are congruent by the Same-Side Interior Angles Theorem. Angles BAC and DCA are congruent by the Alternate Interior Angles Theorem.

Opposite angels are congruent (D = B). Consecutive angles are supplementary (A + D = 180°). If one angle is right, then all angles are right. The diagonals of a parallelogram bisect each other.

Angle Properties, Postulates, and Theorems. ... Angles are congruent if their measures, in degrees, are equal. Note: "congruent" does not mean "equal." While they seem quite similar, congruent angles do not have to point in the same direction.

Yes, if both pairs of opposite angles are congruent, then you have a parallelogram. These are all sufficient conditions to have a parallelogram.

ANSWER: Show that a pair of corresponding angles is congruent, show that a pair of alternate interior angles is congruent, show that a pair of alternate exterior angles is congruent, or show that a pair of consecutive interior angles is supplementary.

The angles of a square are all congruent (the same size and measure.) Remember that a 90 degree angle is called a "right angle." So, a square has four right angles. Opposite angles of a square are congruent. Opposite sides of a square are congruent.

The only time two arcs are congruent is when they have the same length measure, not the same degree measure. ... Two arcs are congruent if and only if they have the same measure within one circle or within two congruent circles.

Vertical angles are always equal in measure. Vertical angles are congruent. Vertical angles, such as ∠1 and ∠2, form linear pairs with the same angle, ∠4, giving m∠1 + m∠4 = 180 and m∠2 + m∠4 = 180.

The included angles must be congruent, and the ratios of the two corresponding sides must be equal. If both criteria are satisfied, then the triangles are similar. ... because the ratios are equal, the triangles are similar by the Side-Angle-Side postulate.

Right Angle Congruence Theorem All right angles are congruent. Theorem If two congruent angles are supplementary, then each is a right angle. Angle Bisector Theorem If a point is on the bisector of an angle, then it is equidistant from the sides of the angle.

Congruent triangles have corresponding sides of equal length and corresponding angles of equal measure. They are the same exact size and shape. is equilateral and is isosceles, so they are not the same exact shape. ... All congruent triangles are similar, but these triangles are not congruent.

Angles are congruent if they have the same angle measure in degrees. They can be at any orientation on the plane. In the figure above, there are two congruent angles. ... To be congruent the only requirement is that the angle measure be the same, the length of the two arms making up the angle is irrelevant.

If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion.

Two figures are congruent if they have the same shape and size. Two angles are congruent if they have the same measure. Two figures are similar if they have the same shape but not necessarily the same size. All of the figures below are congruent since they all have the same shape and size.
