# Maths Questions for DSSSB Exam : 1st August 2018 (Solutions)

Dear Students!!! There is most general as well as a scoring section in all the competitive entrance examinations in the teaching field i.e “Mathematics”.Because in this section only one thing is work i.e your accuracy and that could be nourished with the daily practice. So, for this, we are providing you the daily quiz for all teaching exams i.e CTET Exam 2018, DSSSB Exam & STET Exam.

Solutions
S1. Ans.(b)
Sol. In ∆ABC and ∆DEF,
BC = DE, AB = EF and ∠B = ∠E
If two sides and the included angle of one triangle are equal to the corresponding sides and the included angle of another triangle, then the triangles are congruent by the SAS criterion.
S4. Ans.(c)
Sol. A convex polygon is a polygon that has no portions of their diagonals in their exteriors.

S9. Ans.(b)
Sol. An angle that is greater than 180° is a reflex angle.
S10. Ans.(b)
Sol. When a square is rotated on its diagonal as its axis of rotation, the spindle shape is formed.
