![]() Really Hard Questions with Answers If youre looking for some tough. Statements Reasons 1) QT / PR = QR / QS 1) Given 2) QT / QR = PR / QS 2) By alternendo 3) ∠1 = ∠2 3) Given 4) PR = PQ 4) Side opposite to equal angles are equal. The difficulty level of math equations depends on the age and level of the person. If you flip/reflect MNO over NO it is the 'same' as ABC, so these two triangles are congruent. So if you have two triangles and you can transform (for example by reflection) one of them into the other (while preserving the scale), the two triangles are congruent. Statements Reasons 1) AB = DP ∠A = ∠D and AC = DQ 1) Given and by construction 2) ΔABC ≅ ΔDPQ 2) By SAS postulate 3) AB ACĭE DF 4) By substitution 5) PQ || EF 5) By converse of basic proportionality theorem 6) ∠DPQ = ∠E and ∠DQP = ∠F 6) Corresponding angles 7) ΔDPQ ~ ΔDEF 7) By AAA similarity 8) ΔABC ~ ΔDEF 8) From (2) and (7)ġ) In the given figure, if QT / PR = QR / QS and ∠1 = ∠2. Basically triangles are congruent when they have the same shape and size. ![]() We use these similarity criteria when we do not have the measure of all the sides of the triangle or measure of. Since the points, lines, and angles in taxicab geometry are the same as in Euclidean geometry, taxicab geometry satisfies most of the postulates of Euclidean geometry, including the parallel postulate. However, instead of using the Euclidean distance function. ![]() We can find out or prove whether two triangles are similar or not using the similarity theorems. Taxicab geometry uses the same points, lines, and angles as in Euclidean geometry. ![]() Given : Two triangles ABC and DEF such that ∠A = ∠D AB ACĬonstruction : Let P and Q be two points on DE and DF respectively such that DP = AB and DQ = AC. Formula for Similar Triangles in Geometry: A E, B F and C G AB/EF BC/FG AC/EG Similar Triangles Theorems. SAS Similarity SAS Similarity : If in two triangles, one pair of corresponding sides are proportional and the included angles are equal then the two triangles are similar. SAS Similarity : If in two triangles, one pair of corresponding sides are proportional and the included angles are equal then the two triangles are similar. ![]()
