Tim wrote the following statement: "You can only draw one unique isosceles triangle that contains an angle of 70°."

Which statement is true? (1 point)

a
Tim is incorrect, because more than one triangle can be drawn with the given information.

b
Tim is correct, because only one unique triangle can be drawn with the given information.

c
Tim is incorrect, because the triangle described cannot be drawn with the given information.

d
None of the above.

My answer would be: Tim is incorrect, because more than one triangle can be drawn with the given information.

Given:

Isosceles triangle and has a 70° angle.

An isosceles triangle is a triangle that has 2 congruent angle. Since all interior angle must have a sum of 180°, the possible angles of an isosceles triangle with a 70° angle are:

1) 180° - 70° = 110°

110° / 2 = 55°

Angles are 70°-55°-55°

2) 180° - 70° = 110°

110° - 70° = 40°

Angles are 70°-70°-40°

The given information can create 2 isosceles triangle. Thus, Tim is wrong in his claims.

You're welcome!
