Answer:

Option: A is the correct answer.

A. at least two congruent sides.

Step-by-step explanation:

Isosceles Triangle--

An isosceles triangle that has two sides of equal length.

Sometimes we may consider it as a triangle with at least two sides of equal length( and such a triangle is known as a equilateral triangle)

or we may say that a equilateral triangle is an special case of isosceles triangle.

        Hence, An isosceles triangle has:

          A) at least two congruent sides

Answer:

A. at least two congruent sides

Step-by-step explanation:

Since, we know that,

'An isosceles triangle is a triangle having two sides of equal length or at least two sides of equal length (special case is equilateral triangle)'.

Thus, from the options, we see that,

Options B, C and D are not correct.

<em>Since, congruent sides means that the lengths of the sides are equal.</em>

Thus, we get that,

'An isosceles triangle has at least two congruent sides'.

Hence, option A is correct.

A system of equations has infinitely many solutions. If 2y - 4x = 6 is one of the equations, which could be the other
Serjik [45]

Answer:

-y = -2x - 3

Option 3

Step-by-step explanation:

When equations are equivalent, they will have infinitely many solutions.

If you want to find an equivalent equation, you can <u>multiply/divide every</u> term in the equation by the same number. You can also <u>rearrange</u> the equation.

Since the options mostly have "y" by itself, start by <u>rearranging</u> to isolate "y" in the given equation.

Move all the other numbers to the right of the equal sign except for "y". To move a number, apply its reverse operation to the entire equation.

Do reverse operations in reverse BEDMAS order.

2y - 4x = 6                Move "-4x" first. It's reverse is +4x.

2y - 4x + 4x = 6 + 4x

2y = 6 + 4x                Move the "2" in 2y. Divide the whole equation by 2.

2y/2 = 6/2 + 4x/2

y = 3 + 2x                  Rearrange to look like the answer choices.

y = 2x + 3

This equation looks like option 3 except every term has a different negative/positive.

y = 2x + 3         -y = -2x - 3

We can <u>multiply every term</u> by -1.

y = 2x + 3

y*-1 = 2x*-1 + 3*-1

-y = -2x + (-3)                Negative and positive make a negative

-y = -2x - 3                     Same as option 3

What is an angle whose vertex is the center of the polygon whose sides are drawn totwo consecutive vertices
Sliva [168]

Answer:

A central angle of a regular polygon is an angle whose vertex is the center and whose sides contain two consecutive vertices of the polygon. You can divide 360° by the number of sides to find the measure of each central angle of the polygon.
