Can you match the teacher's comments to the definitions? Definition of a circle
Teacher's comments
Ivy's definition: A 2D geometric shape that is both round
and closed, having no corners.
Correct! Your definition is very clear and
precise.
Ethan's definition: Given a distance r (call it the radius), a
circle is the set of all points r units away from some fixed
point C (call it the center) in a plane.
Sorry, this is incorrect. An ellipse, for
example, would also fit your definition.
Ebuka's definition: A 2-dimensional shape made by drawing
a curve that is always the same distance from a center.
Your definition is close, but it isn't precise
enough. A half-circle, for example, would
also fit your definition.

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

answer: answer: d) v= 1/6 bh  

step-by-step explanation:

since according to the given question,   a pyramid is placed inside a prism.

step-by-step explanation:

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
