Questão 1
Responda
-
The angle at the circumference is half that at the center
-
The angle at the circumference is double that at the center
-
Angles in isosceles triangles are equal
Questão 2
Questão
Angle x = [blank_start]100[blank_end] because angles at the center of a circle [blank_start]are double that at the circumference[blank_end].
Also y = [blank_start]80[blank_end] [blank_start]for the same reason[blank_end].
