Answer:

To prove a triangle is isosceles, it can be used the distance formula to see if at least two sides are congruent.

Step-by-step explanation:

An isosceles triangle is a triangle in which two sides are equal in length. The sides are called equal sides, and the last side unequal to them is called the base. By definition, every regular triangle is also isosceles, but the converse is not true.

If a triangle has two equal sides, then these sides are called the lateral sides, and the third side is called the base. The angle formed by the sides is called the vertex angle, and the angles, one of the sides of which is the base, are called the corners at the base.

A triangle with two equal sides has one axis of symmetry, which passes through the vertex angle and the middle of the base. This axis of symmetry coincides with the bisector of the vertex angle, the median drawn to the base, the height drawn from the vertex corner and the middle perpendicular.

Is my answer correct??
Studentka2010 [4]

Answer:

<u></u>

  • <u>The correct answer is the first choice: Hinge Theorem.</u>

Explanation:

The <em>Hinge Theorem</em> compares the lengths of two sides of two triangles, given that the other two pairs of sides are congruent and the included angles are different.

The theorem states that if two sides of a triangle are congruent to two sides of another triangle and the included angle of one triangle is greater than the included angle of the other triangle, then length of the third side of the first triangle is greater than the length of the third side of the second triangle.

The figures shows triangles UVT and STV

The angle UVT is greater than the angle STV.

The sides ST and VU are congruent, as the small vertical marks indicate.

The side TV is a common side of both triangles.

Then, you already have that two sides of the triangle STV are congruent to two sides of triangle UVT and the angle UVT is greater than the angle STV.

Hence, by the HInge Theorem the side TU is greater than side SV.

The issue of corporate tax reform has been cause for much debate in the United States. Among those in the legislature, 27% are R
Ilia_Sergeevich [38]

Answer:

The probability Democrat is selected given that this member favors some type of corporate tax reform is 0.6309.

Step-by-step explanation:

Let us suppose that,

R = Republicans

D = Democrats

I = Independents.

X = a member favors some type of corporate tax reform.

The information provided is:

P (R) = 0.27

P (D) = 0.56

P (I) = 0.17

P (X|R) = 0.34

P (X|D) = 0.41

P (X|I) = 0.25.

Compute the probability that a randomly selected member favors some type of corporate tax reform as follows:

P(X)=P(X|R)P(R)+P(X|D)P(D)+P(X|I)P(I)\\= (0.34\times0.27)+(0.41\times0.56)+(0.25\times0.17)\\=0.3639

The probability that a randomly selected member favors some type of corporate tax reform is P (X) = 0.3639.

Compute the probability Democrat is selected given that this member favors some type of corporate tax reform as follows:

P(D|X)=\frac{P(X|D)P(D)}{P(X)} =\frac{0.41\times0.56}{0.3639}=0.6309

Thus, the probability Democrat is selected given that this member favors some type of corporate tax reform is 0.6309.
