Cole says that all quadrilaterals are polygons but not all polygons are quadrilaterals is he correct explain������
zepelin [54]
YES, this is correct. All quadrilaterals whether is a trapezoid, parallelogram, rhombus and others, they are all polygons and all they have 4 sides and 4 angles. We know that a polygon is a figure with at least three sides and three angles.

Not all polygons are quadrilateral, this is also correct since some polygons have five or more sides and angles.

The three angle bisectors of ΔABC intersect at point P. Point P is the
lisabon 2012 [21]
<h3>Answer: C) incenter</h3>

========================================

Explanation:

If you were to intersect the angle bisectors (at least two of them), then you would locate the incenter. The incenter is the center of the incircle which is a circle where it is as large as possible, but does not spill over and outside the triangle. Therefore this circle fits snugly inside the triangle.

--------------

extra notes:

* The centroid is found by intersecting at least two median lines

* The circumcenter is found by intersecting at least two perpendicular bisector lines

* The orthocenter is found by intersecting at least two altitude lines

* The incenter is always inside the triangle; hence the "in" as part of the name. The centroid shares this property as well because the medians are completely contained within any triangle. The other two centers aren't always guaranteed to be inside the triangle.

* The red lines cut each angle of the triangle into two equal or congruent pieces.

A recipe calls for 3 cups of flour, 2 cups of sugar and 1 cup of milk. Mason is going to use 7 cups of sugars instead. how much
AlexFokin [52]

Answer:

We need to make a conversion for the new recipe. If the regular recipe calls for 2 cups of Sugar, we can make a conversion for the new recipe.

Step-by-step explanation:

Conversion- 2:7= 1:4  (sugar)

2:7 (sugar)

3: x (flour)

1: y (milk)

X= 8 (flour)

Y= 6 (milk)

NEW RECIPE:

3.5 cups of milk

10.5 cups of flour

7 cups Sugar

We found this by seeing the new recipe adds 5 more cups with the original amount :)
