Answer:
If the interior angles of quadrilaterals STUV and WXYZ are equal then the quadrilaterals, STUV and WXYZ were similar.
Step-by-step explanation:
Quadrilaterals are polygons with four sides.
Similar polygons are in identical form, but can be variant magnitudes.
Two polygons can be considered as similar if the following two things are accurate:
1. The corresponding sides of each polygon are in the same proportion
2. The corresponding interior angles are the equal (congruent).
So, if the interior angles of quadrilaterals STUV and WXYZ are equal then the quadrilaterals, STUV and WXYZ were similar.
Molly would need 43 feet of fencing to fence the area.
Step-by-step explanation:
We can see that the area is in the form of a right-angled triangle. Since only two sides of the triangle is given, we could utilise Pythagoras theorem to our advantage to find out the third side.
In Δ ABC
AB² (base) + AC² (perpendicular) = BC² (hypotenuse)
Substituting the values of AB as 10 feet and BC as 18 feet
AC²= BC²- AB
²
∴AC²= 224
∴AC= 14.96 cm
Amount of fence required by molly would equal perimter of the area.
⇒The perimeter of the area would equal AB+BC+AC
⇒Summing up the values of AB, AC and BC
Perimeter= 10+14.96+18= 42.96 feet which is about 43 feet
Hence, Molly would require 43 feet of fencing.
Answer:
Perpendicular
Step-by-step explanation:
Perpendicular lines meet at a 90 degree angle.
A=17 b = 12
a x b
17 x 12
=204
