MCQ

In a right-angled triangle ABC, if angle B = 90°, then which of the following is true?

Options

  • AB2 = BC2 + AC2

  • AC2 = AB2 + BC2

  • AB = BC + AC

  • AC = AB + BC

Solution

AC2 = AB2 + BC2

Explanation:

According to Pythagoras theorem,

(Hypotenuse)2 = (Perpendicular)2 + (Base)2

⇒ AC2 = AB2 + BC2

  Is there an error in this question or solution?

Activity: From given figure, In ∆ABC, ∠ABC = 90°, ∠ACB = 30°

∴ ∠BAC = `square`

∴ ∆ABC is 30° – 60° – 90° triangle

∴ In ∆ABC by property of 30° – 60° – 90° triangle.

∴ AB = `1/2` AC and `square` = `sqrt(3)/2` AC

∴ `square` = `1/2 xx 12` and BC = `sqrt(3)/2 xx 12`

∴ `square` = 6 and BC = `6sqrt(3)`
