close all
clear all
clc
a=2; %a link length
b=5; %b link length
P1=[0,0];
axis([-2,7,-2,3]);
theta=pi/2;
alfa=asin(a*sin(theta)/b);
P2=a*[cos(theta),sin(theta)];
P3=[(a*cos(theta)+b*cos(alfa)),0];
crank=line([P1(1),P2(1)],[P1(2),P2(2)]);
slider=line([P2(1),P3(1)],[P2(2),P3(2)]);
ground=line([P1(1),P3(1)],[P1(2),P3(2)]);

How do I fill the area inside the Crank-Slider-Ground lines with color?

Thank you, but in the case of 90 <theta <270, I can't get results. (F.e. Theta = 100 deg)
