What does the Angle-Angle Criterion tell you about the relationship between two triangles? If two angles in one triangle are congruent to two angles in another triangle, the two triangles are similar.
If any one angle in one triangle is congruent to an angle in another triangle, the two triangles are similar.
If two angles in one triangle are congruent to two angles in another triangle, the two triangles are congruent.
If all three angles in one triangle are congruent to the angles in another triangle, the two triangles are congruent.

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
