Constructing Triangles: Types of Geometric Construction

Here you have a link of a web page called Study.com with a video you can watch as many times as you need to rehearse and learn how to construct triangles. I hope is useful for you all!

Exercises:

1ST INCENTER OF A TRIANGLE

TRIANGLE GIVEN 3 SIDES

 Data: a= 6cm  b=3,5 cm c=4cm

2ND TRIANGLE KNOWING 2 SIDES AND THE ANGLE THEY FORM. MEDIANS AND CENTROID.

Data:  side a= 4cm

 b= 4,5 cm

angle C= 30 degrees.

3RD TRIANGLE KNOWING THE SIDE AND THE ADJACENT ANGLES B AND C. ORTHOCENTRE AND ALTITUDES.

Data: a 4,5 B= 60 degrees C= 45 degrees

Draw first the angles as Data and them copy them with the compass.

4TH RIGHT TRIANGLE KNOWING ONE LEG AND THE ADJACENT ANGLE. CIRCUMCENTER AND CIRCUMSCRIBED CIRCLE

Data: b = 4 cm, angle C = 30 degrees.

Draw first the angles as Data and them copy them with the compass.

5TH DRAW A RIGHT TRIANGLE KNOWING THE HYPOTENUSE AND ONE LEG

Data: hyponetuse 47mm leg a= 2cm

6TH DRAW AN ISOSCELES TRIANGLE KNOWING THE BASE AND THE ALTITUDE

Data: base a= 3cm  ha= 4cm
