Answer: 81.33 square units


Step-by-step explanation:

Given sides of triangle = 12,14 and 16 are the a,b and c respectively.

Thus the perimeter of triangle =a+b+c=12+14+16=42

The semi perimeter of triangle s=\frac{42}{2}=21

By Heron's formula

Area of triangle = \sqrt{s(s-a)(s-b)(s-c)}

=\sqrt{21(21-12)(21-14)(21-16)}\\\\=\sqrt{21(9)(7)(5)}\\\\=\sqrt{6615}\\=81.3326\approx81.33\text{ square units}

The area of triangle =81.33 square units.

A parallelogram is a quadrilateral with opposite sides parallel (and therefore opposite angles equal).

  • The first one is a parallelogram because, the angle are shown are alternate interior angles which defined between two parallel lines.

  • The second one is not a parallelogram because, the angle are shown are alternate interior angles which should defined between two parallel lines. But there are no parallel lines.

  • The third one is not a parallelogram because, the parallelogram have opposite angles are equals not the adjacent angle.

Hey! can someone please give me ideas on what type of art i could make, thanks im so confused
pogonyaev

Alright, so uno.

By six types of triangles, I'll assume that your teacher meant acute, right, obtuse, scalene, isosceles, and equilateral.

Some easy things to make with triangles are flags.

You could make a triangular leaf, with triangles as the stem.

Look up animals made out tangram triangles for some inspiration.

Honestly, just do whatever you wanna do.
