olga nikolaevna [1]

Answer:

A. Point H is the center of the circle that passes through points D, E, and F.

C. Line segment H E is-congruent-to line segment H D

The center of a circle is a point within it that has the same distance to all other points on its circumference.

Constructing a circle with center H would pass through the points D, E and F at the three vertices of the given triangle. Thus producing a circumscribed circle to the triangle. A circumscribed circle is one that can is constructed outside a given figure.

It can also be observed that, DH ≅ EH ≅ FH. So that, the line segment HE is congruent to line segment HD.

The correct options in the given question are: A and C.

HELP! Malik considers the enlargement of the trapezoid. What is the correct cross product that he should use to solve for the mi
koban [17]

Answer:

C. (18)(25) =10x

Step-by-step explanation:

Malik considers the enlargement of the trapezoid. The side with the length 10 cm becomes the side with the length 25 cm, the side with the length 18 cm becomes the side with x cm.

Write a proportion of corresponding sides:

\dfrac{10}{25}=\dfrac{18}{x}

Cross multiply:

10\cdot x=18\cdot 25,

so correct option is C,

(18)(25) =10x
