Answer:
Lisa is correct as only one triangle with measures 65°, 65° and 50° can be drawn.
Step-by-step explanation:
We are given that, 'The measure of an angle in the Isosceles triangle is 65°'.
Since, 'In an isosceles triangle, the angles opposite to the equal sides have same measure'
So, in the given triangle, two of the angles will have measure equal to 65°.
Also, as The sum of the angles in a triangle is 180°.
Thus, 65° + 65° + x = 180°
i.e. x = 180° - 130°
i.e. x = 50°
Thus, the third angle will have the measure 50°.
Hence, Lisa is correct as only one triangle with measures 65°, 65° and 50° can be drawn.
