Classify the following triangle check all that apply

C. Acute.

E. Scalene

Step-by-step explanation:

We have been given a triangle with angles 51, 59 and 70 degrees. We are asked to classify the given triangle.

A. Obtuse.

Since no angle of our given triangle is greater than 90 degrees, therefore, it is not an obtuse triangle.

B. Isosceles

Since two angles of our given triangle are not equal, therefore, it is not an isosceles triangle.

C. Acute.

Since all angles of given triangle are less than 90 degrees, therefore, our given triangle is an acute triangle.

D. Equilateral.

Since all angles of given triangle are not 60 degrees, therefore, our given triangle is an equilateral triangle.

E. Scalene

Since all sides of given triangle are not equal, therefore, our given triangle is a scalene triangle.

F. Right

Our triangle has not a 90 degree angle, therefore, it is not a right triangle.

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'.
