Answer:
KITE, TRAPEZIUM and A Concave quadrilateral
Step-by-step explanation:
PARALLELOGRAM: A quadrilateral in which opposites sides are PARALLEL and EQUAL.
So, Any quadrilateral which does NOT have its opposite sides being parallel or equal is not a parallelogram.
So, such quadrilaterals are:
1. KITE : A kite is not a parallelogram as it has no parallel lines at all.
2. TRAPEZIUM : A trapezium has ONLY ONE pair of opposite sides parallel.
3. A Concave quadrilateral does not have parallel sides.
Answer:
-2 or -14/7 (they're the same)
Step-by-step explanation:
- Write it out:
- Simplify. It should now look like this:
- Turn -3 2/7 into an improper fraction. It should now look like this: -19/7
- Add:

It isn'ta because hundredth is smaller than tenths
Answer:
The answer is below
Step-by-step explanation:
We are asked to find the perimeter of triangle CDE. The perimeter of a shape is simply the sum of all its sides, hence:
Perimeter of tiangle CDE = |CD| + |DE| + |CE|
Given that C(4, -1), D(4, -5), E(2, -3).
The distance between two points
is given as:

Therefore the lengths of the triangle are:

Perimeter of CDE = 4 + 2.83 + 2.83 = 9.66 units
