Either my brother or his friends is lying.
Read each sentence to find out whether there is any error in it. The error, if any, will be in one part of the sentence. Mark the part with the error as your answer. If there is no error, mark "No Error" as your answer. (Ignore the errors of punctuation).Solution
Replace ‘is’ with ‘are’. In the sentence of ‘either..or’ type, the verb takes the form of the noun closest to it. Here ‘friends’ is plural, thus plural verb ‘are’ will be used.
The vertices of a triangle are given as (5, 4), (9, 6), and (1, 5). Determine the area enclosed by this triangle.
- In triangle MNO, PQ is drawn parallel to side NO. If MP = 5 cm, PN = 10 cm and MQ = 6 cm, find MO.
Two triangles DEF and XYZ are congruent to each other such that DE = 10 cm, YZ = 24 cm, and ∠DEF = ∠XYZ = 90⁰. Find the circumradius of ΔDEF.
...In the given figure, AB ∥ QP, AB = x, PQ = x + 10, RB = x/2, BP = x + 1. Find PQ.

- Find the altitude of an equilateral triangle whose side is 8√3 cm.
An equilateral triangle ABC is surmounted on a square BCDE whose area is 500 cm². Find the altitude of triangle ABC.
If each side of an equilateral triangle is 12 cm, then its altitude is equal to:
In a right triangle, if the altitude drawn to the hypotenuse divides the triangle into two triangles of equal area, what is the value of the smallest an...
