hey yall im confused for number 4 i put given but my teacher said correct 4 mark what you know so you can know what postulate to use .can someone explain.(i will mark you as the branlest wtv)

Step-by-step explanation:

3) LN≅ LN               Reflexive property

4) ΔONL ≅ΔMLN    Given

5) LM ≅ NO              CPCT - Corresponding parts of congruent triangles

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'.
