For a 30 sided regular polygon, We can divide the polygon (30 sides) into 30 inscribed triangles  with central vertex angles of = \frac{360}{30} =12^{o}.

This central vertex angle of <u>12 degrees</u> is the degree of rotation for a 30 sided polygon.

In other words, the 30 sided polygon has <u>12 degree</u> rotational symmetry about the center.

Proofs and congruent triangles ( serious full answers only or 1 star and report )
krok68 [10]

Answer:

<em>There are 5 ways to find if two triangles are congruent.</em>

<em>SSS-</em><em> {Side Side Side Congruence.}</em>

<em>This law of congruence states that if we have two triangles, each with the same measures on each 3 sides it deems the triangles congruent.</em>

<em>SAS- </em><em>{Side Angle Side Congruence.}</em>

<em>This law of congruence states that if we have two triangles, with 2 equal sides and one angle which is common among them; the triangles are congruent.</em>

<em>ASA- </em><em>{Angle Side Angle Congruence.}</em>

<em>This law of congruence states that if we have two triangles, with 2 congruent angle measures and 1 congruent side; the triangles are indeed congruent.</em>

<em>AAS- </em><em>{Angle Angle Side Congruence.}</em>

<em>You may be wondering how this law of congruence differs from the previous one. </em><em> ASA </em><em>refers to any two angles and the included side, whereas </em><em>AAS </em><em>refers to the two corresponding angles and the non-included side.</em>

<em>HL- </em><em>{Hypotenuse Leg Congruence.}</em>

<em>This law of congruence states that if we have two triangles, with a common (congruent) leg and hypotenuse; the triangles are congruent.</em>

Multiply (3x2-4x+5)(x2-3x+2)
Iteru [2.4K]

So with this, you can rewrite the equation as: (3x^2\times x^2)+(3x^2\times -3x)+(3x^2\times 2)+(-4x\times x^2)+(-4x\times -3x)+(-4x\times 2)+(5\times x^2)+(5\times -3x)+(5\times 2)

Firstly, solve the multiplication: 3x^4+(-9x^3)+6x^2+(-4x^3)+12x^2+(-8x)+5x^2+(-15x)+10

Next, combine like terms, and <u>your answer will be: 3x^4-13x^3+23x^2-23x+10</u>
