CONSTRUCCIÓN DE TRIANGULOS

Aquí podéis descargaros las fotocopias de los triángulos para terminar la tarea.

RECTAS NOTABLES DE UN TRIANGULO

En esta página web la escuela en casa podreis ver las construcciones paso a paso. Espero que os sea útil.

Basic geometric constructions

Download here the ppt here with the basic geometric constructions with the compass:
Perpendicular bisector
Angle bisector
Transfer an angle
Draw a triangle

Concurrent lines in a Triangle.

Here you have a video explanation about concurrent lines also called, notable points and lines of the triangle that we learnt in class. I hope is usefull for you to study.

 PPT presentation with the theory of concurrent lines

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

Documentales Online Geometría Fractal

Por si alguna vez os preguntais para que sirve eso de la geometría....Os recomiendo mucho veros este documental.
