An equilateral and right triangle are contradictory.

A triangle is classified as a scalene triangle if all three of its sides have different lengths and all three of its angles are different. Therefore, if triangle PQR has at least two sides that are equal in length, it contradicts the definition of a scalene triangle. Additionally, if any two angles in triangle PQR are equal, this would also contradict its classification as a scalene triangle, since scalene triangles cannot have any equal angles.
Conventionally you use the symbol that looks like an "equals" sign but consists of three lines. It is the same symbol as is used for identities. ABC ≡ PQR
false
An equilateral and right triangle are contradictory.
PQ ST
False. If ABC definitely equals DEF equals MNO and MNO equals PQR then ABC does not equal PQR by the transitive property.
false
True, ABC is congruent to PQR by the transitive property.

Since the sides of triangle are equal, the triangles are equilateral. Just for your information, in this question, we do not require the length of sides. It is just additional information. :) The area of equilateral triangle is: (√3)/4 × a², where a is the side of the equilateral triangle. For triangle ABC, area will be = (√3)/4 × a² (Let 'a' is the side of triangle ABC) Since, side of triangle PQR is half that of ABC, it will be = a/2 Therefore, area of triangle PQR = (√3)/4 × (a/2)² = (√3)/16 × a² Take the ratio of areas of triangle ABC and PQR: [(√3)/4 × a²] / [(√3)/16 × a²] = 4:1

m = pqr/s Multiply both sides by s: ms = pqr Divide both sides by pq: ms/pq = r
