Can someone please help me with this geometry proof? It needs to get done ASAP and I'm really struggling.
1 answer:
One way to prove that the triangles are congruent is to show that the three pairs of sides have the same length.
For side , this is easy, since it is shared by the two triangles, so it is obviously equal.
On the other hand, we know that the given figure is a parallelogram, the opposite sides are equal in length. Particularly, it means that:
Thus, we have shown that each pair of sides have the same length, which means that:

<h3>What is meant by definite integral?</h3>
A definite integral uses infinitesimal slivers or stripes of the region to calculate the area beneath a function. Integrals can be used to represent a region's (signed) area, the cumulative value of a function changing over time, or the amount of a substance given its density.
Definite integral, a term used in mathematics. is the region in the xy plane defined by the graph of f, the x-axis, and the lines x = a and x = b, where the area above the x-axis adds to the total and the area below the x-axis subtracts from the total.
If an antiderivative F exists for the interval [a, b], the definite integral of the function is the difference of the values at points a and b. The definite integral of any function can also be expressed as the limit of a sum.
Let the equation be
substitute the values in the above equation, we get
= on [2π, 4π],
simplifying the above equation
