GEOGEBRA

Technological advances have entered into many areas of life,

ranging from education, economics, business, industry, health, and others.

Especially in the field of education, the manufacture of teaching materials,

research simulations, data visualization, and others can be done by

utilizing technological advances, for example by using computers.

Computers are products of sophisticated technology to make it easier for

humans to do their jobs. Through the use of computers, work becomes

more effective, efficient, and has better measurement accuracy than

manually. In geometry mathematics learning, there are application

programs that can be used to overcome the less accurate depiction of

mathematical objects, complex calculations and spend a lot of time, and

monotonous learning media, one of which is by using geogebra software.

GeoGebra is a free software based on mathematics learning

developed by Markus Hohenwarter from Austria. Geogebra is a computer

program to teach mathematics, especially geometry and algebra

(Hohenwarter, 2008). Meanwhile, Syahbana (2016: 2) says that the

geogebra program is a dynamic program that has facilities to visualize or

demonstrate mathematical concepts. According to (Yuliardi, 2013), a

number of studies have shown that GeoGebra can encourage students'

discovery and experimentation processes in the classroom. GeoGebra is a

program that is quite effective and efficient to help visualize mathematical

objects, especially in function and graph material.

GeoGebra can be used to explore geometric concepts, visualize

geometric objects clearly, accurately, and efficiently, and make it easier to

show the properties of a geometric object. Utilization of the GeoGebra
