Question

Which of the following statements is/are true?
Area of ∆CBD = AC × AB.
B. A right triangle cannot contain an obtuse angle
C. The sum of the angles in any quadrilateral is 360◦
.
1. Only A 2. Only B 3. Only C
4. Only A and B 5. Only B and C


NB:SEE PICTURE I POSTED BELOW

Answer 1

Answer:

only C

Step-by-step explanation:

The angles in a quadrilateral add up to 360 degrees

Opposite angles in a cyclic quadrilateral add up to 180 degrees

Statement A is not correct because that is essentially finding the area of the triangle ABC

Statement B is not correct because all angles in a right angled triangle add up to 180 degrees must be more than 90 but less than 180 degrees

Answer 2

Answer:-

• Only (C)

C. The sum of the angles in any quadrilateral is 360◦
