Negate the following statements. In each case, determine which
statement is true, the original statement or its negation.
a) An angle inscribed in a semicircle is a right angle.
b) Every triangle has at least three sides.
c) Every rectangle is a square.
d) There are exactly three points on every line.
e) Through any two distinct points there is at least one
line.
f) Every rectangle has three sides, and all right triangles are
equilateral.
g) Triangle XYZ is...

Write a basic c++ program to check whether a triangle is valid
or not if the three sides are given:
A triangle is valid if the sum of its two sides is greater than the
third side.
Let’s say that a, b, c is the sides of the triangle. A valid
triangle must satisfy all these conditions:
a + b > c
a + c > b
b + c > a
(2 points) Generate random numbers 1-15 inclusive for...

Using Euclid's Propositions I.1-I.17, solve the following
questions:
(a) One of the angles of triangle ABC is obtuse. Prove that the
other two are acute.
(b) Prove that the angles at the base of an isoscles triangle
are acute
(c) Prove that every triangle has at least one altitude that is
interior to it.

2 charges, 21.44 µC each, are located at two vertices B & C
of an equilateral triangle ABC with sides 2 cm each. Another charge
q is located at point A. Calculate q in micro Coulomb so that net
POTENTIAL at the mid point of BC will be ZERO.

2 charges, 14.34 µC each, are located at two vertices B & C
of an equilateral triangle ABC with sides 2 cm each. Another charge
q is located at point A. Calculate q in micro Coulomb so that net
POTENTIAL at the mid point of BC will be ZERO.

2.0 pC charges sit at the vertices of an equilateral triangle of
a side .24 m.
a) Sketch the situation and show the electric field vectors and
show the net electric field at the center of the triangle.
b) Find the electric field at the center of the triangle.
c) Repeat the calculation if one of the charges is replaced by a
-2.0 pC charge.

Three charges, each of charge 5.0 ""C are located at the
vertices of an equilateral triangle whose sides are 10 cm in
length. a) What is the total force, magnitude and direction, on
charge I? b) What is-the total potential energy of the three
charges? c) Charges 2 and 3 remain fixed, but charge one is now
allowed to move. If it starts from rest, what i.s its velocity when
it is very far away from charges 2 and 3?...

C++
1. Modify the code from your HW2 as follows:
Your triangle functions will now return a string object. This string will contain the identification of the triangle as one of the following (with a potential prefix of the word “Right ”):
Not a triangle
Scalene triangle
Isosceles triangle
Equilateral triangle
2. All output to cout will be moved from the triangle functions to the main function.
3. The triangle functions are still responsible for rearranging the values such that...

Find, correct to the nearest degree, the three angles of the
triangle with the given vertices.
A(1, 0, −1), B(4, −4,
0), C(1, 5, 5)
angle CAB = ?
angle ABC = ?
angle BCA = ?
