How do you Prove triangle ACD is congruent to triangle BDC?
Because Corresponding Parts of Congruent Triangles, there are five ways to prove that two triangles are congruent. Show that all sides are congruent. (SSS) Show that two sides and their common angle are congruent. (SAS) Show that two angles and their common side are congruent. (ASA) Show that two angles and one of the non common sides are congruent. (AAS) Show that the hypotenuse and one leg of a right triangle are congruent. (HL)
How can you show that two angles on a triangle are congruent?
you simply cannot
How can transformations show that angles are congruent?
Transformations, such as translations, rotations, and reflections, can demonstrate that angles are congruent by showing that one angle can be mapped onto another without altering its size or shape. For instance, if two angles can be aligned perfectly through a series of transformations, they are considered congruent. This property is fundamental in geometry, as it confirms that congruent angles maintain equal measures, regardless of their position in space. Thus, transformations visually and mathematically establish the congruence of angles.
What else would need to be congruent to show that triangle abc congruent to xyz by asa?
To show that triangle ABC is congruent to triangle XYZ by the ASA (Angle-Side-Angle) criterion, we need to establish that two angles in triangle ABC are congruent to two angles in triangle XYZ, along with the side that is included between those angles being congruent. Specifically, if we have ∠A ≅ ∠X, ∠B ≅ ∠Y, and side AB ≅ XY, then the triangles can be concluded as congruent by ASA. Thus, we would need to confirm the congruence of these angles and the included side.
How do you mark congruent sides and angles?
To mark congruent sides and angles, you use tick marks and arc symbols, respectively. For congruent sides, you place the same number of tick marks on each side to indicate they are equal in length. For congruent angles, you draw arcs along the sides of the angles, using the same number of arcs to show that the angles are equal. This visual representation helps to easily identify congruence in geometric figures.
How do you show that two angles are congruent?
You show that they have the same measure.
How do you show two congruent angles?
the symbol for congruent is ~ with _ in the same space. (US keyboard does not have a congruent key

Are the diagonals of a rectangle congruent always?
Yes. You can show this by SAS of two right triangles. Consider rectangle ABCD. AD and BC are the same length and AC and BD are the same length because opposite sides are congruent. The angles ADC and BCD are congruent since it is a rectangle and the angles are right angles. So the triangles ADC and BCD are congruent and their hypotenuses (the diagonals of the rectangles) are congruent.
Why would you use CPCTC?
Once you have shown that two triangles are congruent you can use CPCTC (corresponding parts of congruent triangles are congruent) to show the congruence of the remaining sides and angles.
How do you mark congruent sides and angles?
To mark congruent sides and angles, you use tick marks and arc symbols, respectively. For congruent sides, you place the same number of tick marks on each side to indicate they are equal in length. For congruent angles, you draw arcs along the sides of the angles, using the same number of arcs to show that the angles are equal.

What else would need to be congruent to show that abc is congruent to def by the aas theorem?
To show that triangles ABC and DEF are congruent by the AAS (Angle-Angle-Side) theorem, you need to establish that two angles and the non-included side of one triangle are congruent to the corresponding two angles and the non-included side of the other triangle. If you have already shown two angles congruent, you would need to prove that one of the sides opposite one of those angles in triangle ABC is congruent to the corresponding side in triangle DEF. This additional information will complete the criteria for applying the AAS theorem.
What is the matching angle mark to indicate which angles are congruent For line AB and CD?
To indicate that angles are congruent, matching angle marks such as arcs or hash marks are typically used. For angles formed by lines AB and CD, you would place the same number of arcs or hash marks in each angle that you want to show as congruent. For example, if angles ∠1 and ∠2 are congruent, you might place one arc in both angles to signify their equality.
What else would be need to be congruent to show that triangle JKL congruent MNO by AAS?
To show that triangle JKL is congruent to triangle MNO by the Angle-Angle-Side (AAS) theorem, you need to establish that two angles and the non-included side of triangle JKL are congruent to two angles and the corresponding non-included side of triangle MNO. Specifically, you would need to verify that one of the angles in triangle JKL is congruent to one of the angles in triangle MNO, and that the side opposite the angle in triangle JKL is congruent to the corresponding side in triangle MNO. This would complete the necessary conditions for AAS congruence.
