What comes next in the sequence: 2, 4, 10, 28, ___ ?
The difference between 2 and 4 is 2
The difference between 4 and 10 is 6 (or 2 from previous x3)
The difference between 10 and 28 is 18 (or 6 from previous x 3)
The difference between 28 and 82 is is 54 (or 18 from previous x 3)
What is the side included between the angles A and B in ΔABC?
Angle A and Angle B have a line as AB , since we have two vertices A and B which gives us the side AB.
In the below quadrilateral ABCD, AD = BC and ∠DAB = ∠CBA. If ΔABD ≌ ΔBAC. The relation between ∠ABD and ∠BAC is
In ΔABD and ΔBAC,
AD = BC (Given)
∠DAB = ∠CBA (Given)
AB = BA (Common)
∴ ΔABD ≅ ΔBAC (By SAS congruence rule)
∴ BD = AC (By CPCT)
And, ∠ABD = ∠BAC (By CPCT)
In the quadrilateral ABCD, AC = AD and AB bisect ∠A and ΔABC ≅ ΔABD. The relation between BC and BD is
In the below figure, AC and BD are equal perpendicular to line segment AB. If ?BOC ≅ ?AOD, then the relation between OC and OD is
In the below figure, AB = AC = CD. If ΔACD ≌ ΔABE then AD =
ΔACD ≌ ΔABE. Here angle A corresponds to Angle A, Angle C with Angle B and Angle D with Angle E, Similarly Side AC corresponds to AB, CD to BE and AD to AE. So AE is the answer.
ΔABC is right triangle in which ∠A = 90° and AB = AC. The values of ∠B and ∠C will be
The measure of each angle of an equilateral triangle is:
If the vertical angle of a isosceles triangle is 40^{°}, then measure of other two angles will be
If ∠A, ∠B and ∠C of ΔABC are equal, then triangle is
Which one of the following is the value of congruency?
We have four congruence criterions namely, SSS,SAS,ASA,RHS. There is no such ASS or SSA criterions
By which congruence rule following triangles are congruent ?
The SSS rule states that:
If three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.
In the below figure, AC = BD and AD = BC. Which of the following statements is meaningfully written?
AC corresponds to BD and AD corresponds to BC. So while writing the name of the triangles the alphabets should be written according to the correspondence. So ΔABC ≅ ΔBAD
Which is the longest side in the triangle ABC right angled at B?
Which is the longest side of a right triangle?
What is the angle included between the sides PN and PM of ΔMNP?
In triangles ABC and PQR, AB = 3.5 cm, BC = 7.1 cm, AC = 5 cm, PQ = 7.1 cm, QR = 5 cm and PR = 3.5 cm, then which of the following is true
A triangle in which all three sides are of equal lengths is called _________.
Equilateral means having all sides equal .So Equilateral triangle has all of its 3 sides equal.
In triangles ABC and DEF, AB = 7 cm, BC = 5 cm, ∠B = 50°, DE = 5 cm, EF = 7 cm, ∠E = 50^{°}. By which congruence rule the triangles are congruent?
Given: AB = EF = 7 cm,
BC = DE = 5 cm and
∠B =∠E = 50°
Also,
A↔F,B↔E,C↔D
By using SAS congruence rule, it can be written as
∆ABC ≅ ∆FED
In the below figure, A B = AC and AD is the bisector of ∠BAC , then the relation between ∠B and ∠C is
AB=AC(given)
∠BAD=∠CAD(angle bisector)
AD=AD(Common)
2)∠ABD≅∠ADC(SAS)
3)∠B=∠C
(because ∠ABD≅∠ADC(SAS)
