Which best explains whether or not all isosceles triangles are similar?

Natali5045456 [20]

Answer:

C: All isosceles triangles are not similar. The pair of congruent angles within one triangle is not necessarily congruent to the pair of congruent angles within the other triangle.

Step-by-step explanation:

An Isosceles triangle is one that 2 of it's sides are equal and thus two of its angles are congruent which means they are equal.

Now, another Isosceles triangle may not necessarily be similar to another one because the congruent angles in one Isosceles triangle may not be the same with that of another Isosceles triangle.

Thus, correct answer is option C

Find the distance between the two points -4,-5 and 2,3. Show your work.

rjkz [21]

Answer

Steps are included the distance formula is the square root of the equation (x2-x1)^2+(y2-y1)^2

$\sqrt{ \left( 2 - -4\right)^2 + \left( 3 - -5\right)^2}\\ \sqrt{ \left( 2 + + 0\right)^2 + \left( 3 + 5\right)^2}\\\sqrt{\left( 6\right)^2 + \left( 8\right)^2}\\\sqrt{ 36 + 64 }\\ \sqrt{ 100 } \approx 10$

your final answer is 10

identify and equation in point-slope form for the line perpendicular to y=-1/2x-7 that passes through (-3,-2)

bazaltina [42]

Answer:

y +2 = 2(x +3)

Step-by-step explanation:

The equation in point-slope form for a line with slope m through point (h, k) is ...

y -k = m(x -h)

The slope of your given line is the coefficient of x, -1/2. The slope of a perpendicular line will be the negative reciprocal of that: -1/(-1/2) = 2. So, you have m = 2, (h, k) = (-3, -2), and your desired equation is ...

y -(-2) = 2(x -(-3)) . . . . . . which can be simplified to ...

y +2 = 2(x +3)
