Question

20. Which of the following statements is true?

a. Two acute angles can form a linear pair

b. Two obtuse angles can form a linear pair

c. Two right angles can form a linear pair

d. One obtuse angle and one acute angle cannot form a linear pair​

Answer 1

Answer:

Because the sum of the measures of two acute angles is always less than 180 degrees, two acute angles can never form a linear pair. No,two obtuse angles can't form a linear pair. as sum of linear pair is 180°, and obtuse angle 180°>90° that's why it can't.

Answer 2

Answer:

Because the sum of the measures of two acute angles is always less than 180 degrees, two acute angles can never form a linear pair. No,two obtuse angles can't form a linear pair. as sum of linear pair is 180°, and obtuse angle 180°>90° that's why it can't.
