A polygon is composed of three or more line segments ,and when you join these segments ,a closed geometrical shape should form.For example, Equilateral triangle, Square, Regular Pentagon, Regular Hexagon,....
There are many possibilities.
→If you join an Equilateral and three other equilateral triangles having same base length,you will obtain, Equilateral Pyramid.
→If you join Square and four equilateral triangles having same base length,you will obtain, Equilateral Square Pyramid.
→Similarly, if you join Regualr Pentagon and five equilateral triangles having same base length,you will obtain, Equilateral Regular pentagonal Pyramid
→Regular Hexagon+Six equilateral triangles=Equilateral Regular Hexagonal Pyramid
→If you join six congruent squares ,you will get the shape of Prism called Cube.
These are known that is defined shape in mathematics which i have written.You can create many more shapes by yourself.

Answer:
<h2>AC = 36.01</h2>Step-by-step explanation:
Given ΔABC and ΔADB, since both triangles are right angled triangles then the following are true.
From ΔADB, AB² = AD²+BD²
Given AB = 24 and AD = 16
BD² = AB² - AD²
BD² = 24²-16²
BD² = 576-256
BD² = 320
BD =
BD = 17.9
from ΔABC, AC² = AB²+BC²
SInce AC = AD+DC and BC² = BD² + DC² (from ΔBDC )we will have;
(AD+DC)² = AB²+ (BD² + DC²)
Given AD = 16, AB = 24 and BD = 17.9, on substituting
(16+DC)² = 24²+17.9²+ DC²
256+32DC+DC² = 24²+17.9²+ DC²
256+32DC = 24²+17.9²
32DC = 24²+17.9² - 256
32DC = 640.41
DC =
DC = 20.01
Remember that AC = AD+DC
AC = 16+20.01
AC = 36.01
