What are three attributes of a parallelogram?
Parallelograms: 1.)opposite side of a parallelogram are parallel and you can prove that by finding the slope for both lines. 2.) opposite sides of a parallelogram are congruent 3.) diagonals bisect each other 4.)opposite angles are congruent 5.) consecutive angles are supp.
what- If you are given or can prove that two triangles are congruent, then you may use CPCTC to prove that the angles or sides are?
congruent
How can you prove that a constructed line is parallel to a given line if the transversal in not perpendicular?
Show that corresponding angles are congruent?
Explain four ways to prove that two triangle are congruent?
one way is to use the corresponding parts. if they are congruent then the two triangles are congruent. i don't know any other ways without seeing the triangles or any given info. sorry i couldn't help more.
What is the ways to prove that a quadrilateral is a parallelogram?
If it is a parallelogram, then it has two sets of parallelogram sides. Parallelograms' opposite angles are congruent A parallelogram's bisectors are congruent. * * * * * A parallelogram's bisectors are NOT congruent.

What are necessary when proving that the opposite angles of a parallelogram are congruent?
To prove that the opposite angles of a parallelogram are congruent, you can utilize the properties of parallel lines and transversals. Since the opposite sides of a parallelogram are parallel, the alternate interior angles created by a transversal are equal. Additionally, you can apply the fact that consecutive angles in a parallelogram are supplementary, leading to the conclusion that if one angle is known, its opposite angle must be equal. Thus, through these properties, you can establish that opposite angles are congruent.
How do you prove opposite angles of a parallelogram are congruent?
Simply with a protractor and the 4 interior angles must add up to 360 degrees
What is necessary to have when proving that the opposite angles of a parallelogram are congruent?
To prove that the opposite angles of a parallelogram are congruent, you need to establish that the figure is indeed a parallelogram, which can be done by showing that both pairs of opposite sides are parallel or that one pair of opposite sides is both equal and parallel. Once this is confirmed, you can use the properties of transversals and corresponding angles, or the fact that consecutive angles are supplementary, to demonstrate that the opposite angles are congruent. Therefore, a clear understanding of the properties of parallelograms and angle relationships is essential for the proof.
If one pair of opposite angles and one pair of opposite sites of a quadrilateral is congruent then the quadrilateral is a parallelogram. How can it be proven?
draw a diagonal through opposite corners of the quadrilateral. This makes two triangles. Prove the triangles are congruent using SSA (side side angle) congruence. Then show that the other two sides of the quadrilater must be congruent to each other, so it is a parallelogram.
What are all of the characteristics of a parallelogram?
Parallelograms: 1.)opposite side of a parallelogram are parallel and you can prove that by finding the slope for both lines. 2.) opposite sides of a parallelogram are congruent 3.) diagonals bisect each other 4.)opposite angles are congruent 5.) consecutive angles are supp. *Remember that alternate interior angles are congruent. To break it down in a better understanding way. 1.)opposite side of a parallelogram are parallel and you can prove that by finding the slope for both lines. If the shape is a parallelogram then you can find the slope of its sides. if they are parallel to each other then it is a parallelogram. 2.) opposite sides of a parallelogram are congruent top and bottom sides are congruent. right and left sides are congruent. 3.) diagonals bisect each other When you draw a straight line from the top right corner to the bottom left corner and from the top left corner to the bottom right corner, the bisect each other or in better terms, the lines cut each other equaly in half. 4.)opposite angles are congruent just as the sides. 5.) consecutive angles are supp. These angels produce a line. this line like all lines will add up to 180 degrees. *Remember that alternate interior angles are congruent.

What are necessary when proving that the oppsite sides of a parallelogram are congruent check all that apply?
To prove that the opposite sides of a parallelogram are congruent, you need to establish that the shape is a parallelogram, which can be done by showing that either pairs of opposite sides are parallel (using the properties of parallel lines) or that the diagonals bisect each other. Additionally, applying the properties of congruent triangles (such as using the Side-Side-Side or Side-Angle-Side postulates) can further support the proof. Ensure to use clear definitions and properties of parallelograms throughout the proof.
Given quadrilateral ABCD with diagonals AC and BD angle 1 is congruent to angle 2 and segment BD bisects segment AC at A prove ABCD is a parallelogram Can someone help me prove this?
To prove that quadrilateral ABCD is a parallelogram, we can use the properties of the angles and the bisected segment. Since angle 1 is congruent to angle 2 and BD bisects segment AC at point A, it follows that triangle ABD is congruent to triangle CDB by the Angle-Side-Angle (ASA) criterion. This congruence implies that sides AB and CD are equal and sides AD and BC are equal, which are the defining properties of a parallelogram. Therefore, quadrilateral ABCD must be a parallelogram.
