Given ABE, ADC, BD bisescts angle ABC and BD is parallel to EC prove: Triangle EBC is isoceles
To prove triangle ABC is congruent to triangle EDC by the SAS (Side-Angle-Side) Postulate, you need to confirm that two sides and the included angle of triangle ABC are equal to the corresponding two sides and the included angle of triangle EDC. Specifically, you need to know the lengths of sides AB and AC, and the measure of angle A in triangle ABC, as well as the lengths of sides ED and EC, and the measure of angle E in triangle EDC. Once this information is established, you can demonstrate the congruence between the two triangles.
The answer depends on what information you already have. Without that knowledge, you cannot even begin to guess what is additional.
If two triangles have the same shape but one is an enlargement of the other they are said to be similar. The two triangles must be equi-angular. To prove that ∆ABC is similar to ∆XYZ it is necessary to prove one of the following :- 1) Two angles in ∆ABC are equal to two angles in ∆XYZ, since it follows that the third angles will also be equal. 2) The three sides of ∆ABC are proportional to the corresponding sides of ∆XYZ AB/XY = AC/XZ = BC/YZ 3) Two sides in ∆ABC are proportional to two sides in ∆XYZ and the angles included between these sides in each triangle are equal. AB/XY = AC/XZ and angle A = angle X.

Here is the answer to your query. Consider two ∆ABC and ∆PQR. In these two triangles ∠B = ∠Q = 90�, AB = PQ and AC = PR. We can prove the R.H.S congruence rule i.e. to prove ∆ABC ≅ ∆PQR We need the help of SSS congruence rule. We have AB = PQ, and AC = PR So, to prove ∆ABC ≅ ∆PQR in SSS congruence rule we just need to show BC = QR Now, using Pythagoras theorems in ∆ABC and ∆PQR Now, in ∆ABC and ∆PQR AB = PQ, BC = QR, AC = PR ∴ ∆ABC ≅ ∆PQR [Using SSS congruence rule] So, we have AB = PQ, AC = PR, ∠B = ∠Q = 90� and we have proved ∆ABC ≅ ∆PQR. This is proof of R.H.S. congruence rule. Hope! This will help you. Cheers!!!

They are congruent when they have 3 identical dimensions and 3 identical interior angles.
(eg. Aa Bb Cc) First would be to find out all the different combinations of these traits ABC ABc AbC Abc aBC aBc abC abc Then would be to make a "cross" out of them ABC ABc AbC Abc aBC aBc abC abc ABC ABc AbC Abc aBC aBc abC abc Then would be to 'fill in' the cross by adding them up ABC ABc AbC Abc aBC aBc abC abc ABC AABBCC AABBCc AABbCC AABbCc AaBBCC AaBBCc AaBbCC.... ABc AbC Abc aBC aBc abC abc Hope the rest you can figure out, Sincerely, *diag*
