Congruence of Triangles
Question 1:
△MNO and △XYZ are congruent under the correspondence. MNO↔XYZ.
Give the answer of following questions from the above figure.
Write the parts △MNO that corresponds to ?
(a) NO
(b) XZ
(c) XY
(d) YZ
Ans
(b) XZ
The correspondence is MNO↔XYZ this means M↔X, N↔Y, O↔Z.
Question 2:
Write of the parts of △MNO that corresponds to ∠y?
(a) ∠X
(b) ∠Z
(c) ∠N
(d) ∠O
Ans:
∠N, the correspondence is MNO↔XYZ this means ∠N↔∠Y.
Question 3:
Write the parts of △MNO that corresponds to ?
(a)
(b)
(c)
(d)
Ans
(a)
The correspondence is MNO↔XYZ this means ↔
Question 4:
Write the parts of △MNO that corresponds to ∠O?
(a) ∠N
(b) ∠M
(c) ∠Z
(d) ∠X
Ans:
(c) ∠Z
The correspondence is MNO↔XYZ this means ∠O↔∠Z
Question 5:
Draw the figure △ABC, AB = 7cm, BC = 4cm ∠B = 60°
Ans:
(b) △ABC draws exactly what say in question.
Question 6:
For As a congruence rule, △MNO ≅ △PQO ← this are the give answers of question from the above figure.
Find ∠M =?
(a) 80°
(b) 90°
(c) 70°
(d) 110°
Ans:
(a) 80°
△MNO, sum of three angle of triangle is 180°, ∠M + ∠N + ∠O = 180°
∠M + 70° + 30° = 180°
∠M = 80°
Question 7:
Find the angle ∠O =?
(a) 40°
(b) 30°
(c) 60°
(d) 50°
Ans:
(b) 30° by △MNO ≅ △PQO
∠MON↔∠POQ
Question 8:
Which sides is congruence to ?
(a)
(b)
(c)
(d) MO
Ans:
(a) , by △MNO ≅ △PQO by ASA congruence rule ← PQ
Question 9:
If △ABC and △PQC are to be congruent, then give the answers of following question.
∠B =? Which is congruent to
(a) ∠Q
(b) ∠C
(c) ∠P
(d) ∠A
Ans:
∠Q (a), both the angle ∠B and ∠Q are right angle so these measure is equal and they are congruent of each other.
Question 10:
Which is congruent side of AC =?
(a) CQ
(b) CP
(c) PQ
(d) AB
Ans:
(b) CP, both triangle △ABC and △CPQ are right △angle triangle and △ABC ≅ △PQC so, it means.
AC = CP
Question 11:
Which angle is congruent to ∠A =?
(a) ∠B
(b) ∠Q
(c) ∠P
(d) ∠C
Ans:
(c) ∠P
Both triangle △ABC and △CPQ are right angle triangle △ABC ≅ △PQC so it means
∠P = ∠P
Question 12:
You want to show that △ART ≅ PEN
Give the answers of following question from the above figure.
If you have to use SSS criterion, then you need to show, (I) AR =
(a) PE
(b) AT
(c) RT
(d) PN
Ans:
(a) PE
SSS congruence of two triangle two triangles are congruent if the three sides of the one are equal to the three corresponding sides of the other RT = EN, PN = AT, AP = PE and also by the right angle triangle.
Two right angle triangle are congruent if the hypotenuse and leg of the one of the triangles are equal to the hypotenuse and the corresponding leg of the other triangle.
△ART ≅ △PEN
Question 13:
Find this property of which congruence of two triangles.
“Two triangles are congruent if two sides and the angle included between them in one of the triangles are equal to the corresponding sides the other angles included between them of the other triangle”
(a) SSS
(b) ASA
(c) SAS
(d) AAA
Ans:
(c) SAS
This is the property of SAS.
Question 14:
“Two triangles are congruent if the three sides of the one are equal to the three corresponding sides of the other”
(a) ASA
(b) SAS
(c) SSS
(d) AAA
Ans:
(c) SSS, SSS congruence of two triangles.
Question 15:
“Two triangles are congruent if two angles and the side included between them in one of the triangles are equal to the corresponding angles and the side included between them of the other triangle”.
(a) ASA
(b) SSS
(c) SAS
(d) AAA
Ans:
(a) ASA,
ASA congruence of two triangles.
