Answer:
1.a - straight angle
1.b - acute angle
1.c - obtuse angle
1.d - straight angle
1.e - obtuse angle
2.a - right angle
2.b - acute angle
2.c - straight angle
2.d - reflex angle
2.e - obtuse angle
Step-by-step explanation:
right angle - exactly 90⁰
acute angle - less than 90⁰
obtuse angle - greater than 90⁰ but less than 180⁰
straight angle - exactly 180⁰
reflex angle - greater than 180⁰ but less than 360⁰
