What are congruence theorems and postulates?
If the sides AB, BC and CA of triangle ABC correspond to the sides DE, EF and FD of triangle DEF, then the two triangles are congruent if:AB = DE, BC = EF and CA = FD (SSS)AB = DE, BC = EF and angle ABC = angle DEF (SAS)AB = DE, angle ABC = angle DEF, angle BCA = angle EFD (ASA)If the triangles are right angled at A and D so that BC and EF are hypotenuses, then the triangles are congruent ifBC = EF and AB = DE (RHS)BC = EF and angle ABC = angle DEF (RHA).
Frances drew ABC and DEF so that A D AB 4 DE 8 AC 6 and DF 12. Are ABC and DEF similar?
To determine if triangles ABC and DEF are similar, we can use the side lengths given. The ratios of the corresponding sides must be equal. For triangle ABC, the sides are AB = 4, AC = 6, and the unknown BC, while for triangle DEF, the sides are DE = 8, DF = 12, and the unknown EF. The ratio of AB to DE is 4/8 = 1/2, and the ratio of AC to DF is 6/12 = 1/2, which are equal. Therefore, triangles ABC and DEF are similar by the Side-Side-Side (SSS) similarity criterion.
Is ABC DEF If so name the congruence postulate that applies.?
Yes, triangles ABC and DEF are congruent if all corresponding sides and angles are equal. The congruence postulate that applies in this case could be the Side-Angle-Side (SAS) postulate, which states that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent. Other applicable postulates include Side-Side-Side (SSS) and Angle-Angle-Side (AAS), depending on the known measurements.
Given that ABC DEF what is the measure of E?
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals" etc. There is, therefore, no visible symbol between ABC and DEF (<, =, >, ≠ etc). Furthermore, there is no information as to whether ABC is an angle, a triangle, an arc.
What is right angle DEF?
It is an angle measuring 90 degrees.
